Technical Field

[0001] The present application relates to the field of network security technology, and in particular to a method, device, electronic device and storage medium for inserting data into an installation package. Background Art

[0002] Client software products are usually provided to customers in the form of software packages, which require compiling binary files, packaging binary files and resource files into installation packages (where different client systems have different installation package formats), and signing the installation package files before publishing them on the website for customers to download. However, the installation packages downloaded by different customers are exactly the same, and it is impossible to provide personalized and differentiated services to each customer. Therefore, it is very important to add user requirements to the installation package.

[0003] The existing technology has many disadvantages when inserting data into the installation package. For example, it increases the installation difficulty for customers and poor user experience; it is necessary to ensure that the file name is not modified after the installation package is downloaded, but in practice, it is easy for the file name to be modified; if the installation package is software for corporate customers, each corporate employee is required to log in separately, which increases the difficulty of deploying the installation package; if the number of customers is very large, generating an exclusive installation package for each customer will result in huge maintenance costs. Summary of the invention

[0004] The purpose of the present application is to provide a method, device, electronic device and storage medium for inserting data into an installation package, which can insert the customer's personalized information into the installation package, so that the installation package can be adaptively adjusted according to the customer's needs, reducing the deployment difficulty of the installation package, facilitating multiple downloads, and reducing maintenance costs.

[0005] In a first aspect, an embodiment of the present application provides a method for inserting data into an installation package, the method comprising: Obtain the user's download requirements; Extracting personalized data from the download request; Selecting an installation type of the installation package according to the installation information in the download requirement; The personalized data is inserted into the corresponding installation package according to the installation type.

[0006] In the above implementation process, different methods are used to insert the user's personalized data into the installation package according to the installation type of the installation package. The customer's personalized information can be inserted into the installation package, so that the installation package can be adaptively adjusted according to customer needs, reducing the deployment difficulty of the installation package, facilitating multiple downloads, and reducing maintenance costs.

[0007] Furthermore, the step of inserting the personalized data into the corresponding installation package according to the installation type includes: If the installation type is the first type, the corresponding installation package is a first file, and the personalized data is inserted into the first file according to a first method to obtain the installation package after the data is inserted; If the installation type is the second type, the corresponding installation package is the second file, and the personalized data is inserted into the second file according to the second method to obtain the installation package after the data is inserted; If the installation type is the third type, the corresponding installation package is a third file, and the personalized data is inserted into the third file according to a third method to obtain the installation package after the data is inserted.

[0008] In the above implementation process, personalized data is inserted in different ways according to the installation type, which can avoid the impact of data insertion on the installation package and improve the stability and operation efficiency of the installation package.

[0009] Furthermore, the step of inserting the personalized data into the first file according to the first method to obtain the installation package after the data is inserted includes: Determining whether the first file contains signature information; If yes, insert the personalized data into the first file according to the signature information to obtain an installation package after the data is inserted; If not, data insertion fails.

[0010] In the above implementation process, it is determined whether the first file contains signature information, and data insertion processing can be performed on the first file according to its characteristics, which can simplify the data insertion process and improve the stability of the first file.

[0011] Furthermore, the step of inserting the personalized data into the first file according to the signature information to obtain the installation package after the data is inserted includes: Filling the personalized data into the signature information to obtain a filled first file; Expanding the filled first file to a first threshold file size to obtain an expanded first file; Obtain a target field in the expanded first file; Verify the target field according to the signature information to obtain a verification result; If the verification result is valid, the target field is overwritten into the file header of the filled first file to obtain the installation package after the data is inserted.

[0012] In the above implementation process, personalized data is filled into the signature information, and then the filled first file is expanded to determine whether the filled first file can be verified. This can improve the data insertion efficiency of the first file and reduce the risk of data insertion failure.

[0013] Furthermore, the step of verifying the target field according to the signature information includes: Obtaining the signature length in the signature information; Obtaining preset length data according to the signature length and the padding length; The length data of the target field is compared with the preset length data. If the length data of the target field is equal to the preset length data, the verification result is valid; if the length data of the target field is not equal to the preset length data, the verification result is invalid.

[0014] In the above implementation process, the preset length data is obtained according to the signature length, and then the preset length is compared with the length data of the target field, which can ensure the rationality and validity of the first file after the data is inserted and improve the availability of the first file.

[0015] Furthermore, the step of inserting the personalized data into the second file according to the second method to obtain the installation package after the data is inserted includes: Determining whether the second file is legal; If so, obtain the structure size of the second file, obtain the end position of the data pile of the second file according to the structure size, insert the personalized data into the second file, and obtain the installation package after the data is inserted.

[0016] In the above implementation process, it is determined whether the second file is legal, and data is inserted into the second file according to its characteristics, simplifying the data insertion process. At the same time, it is ensured that the inserted data will not damage the structure of the second file, thereby effectively maintaining the stability of the second file.

[0017] Furthermore, the step of inserting the personalized data into the third file according to the third method to obtain the installation package after the data is inserted includes: Determining whether the third file is legal; If so, fill a preset data block at the end of the third file, fill the personalized data into the preset data block, obtain the filled third file, expand the filled third file to the second threshold file size, and obtain the installation package after the data is inserted.

[0018] In the above implementation process, data is inserted according to the file characteristics of the third file, so that the personalized data can be completely inserted into the third file without affecting the installation of the third file, thereby improving the efficiency and security of data insertion.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0029] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0030] The specific implementation methods of the present application are further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application, but are not used to limit the scope of the present application.

[0031] Embodiment 1 Figure 1 is a flow chart of a method for inserting data into an installation package provided in an embodiment of the present application, such as Figure 1 As shown, the method includes: S1, obtain the user's download requirements; S2, extracting personalized data from the download requirements; S3, selecting the installation type of the installation package according to the installation information in the download requirement; S4, inserting the personalized data into the corresponding installation package according to the installation type.

[0032] In the above implementation process, different methods are used to insert the user's personalized data into the installation package according to the installation type of the installation package. The customer's personalized information can be inserted into the installation package, so that the installation package can be adaptively adjusted according to customer needs, reducing the deployment difficulty of the installation package, facilitating multiple downloads, and reducing maintenance costs.

[0033] The present application provides a method for inserting personalized data into installation packages of different platforms, which can insert personalized data while the installation package is running without destroying the signature of the installation package, and can provide differentiated installation methods according to user needs.

[0034] In S1 and S2, the user's personalized data is extracted according to the user's download requirements, and the personalized data is used to insert into the original installation package to generate a new installation package, and then the new installation package is returned to the user.

[0035] In S3, the embodiment of the present application implements data insertion by judging the installation type of the installation package. The installation package is formed by packaging binary and resource files. Among them, the installation package on the Windows system is a portable executable file (Portable Executable, PE), the installation package on the macOS system is a PKG file (a software package format), and the installation package of the Xinchuang Tongxin and Kylin desktop system is a DEB file (a software package format), etc. The embodiment of the present application can be applied to a variety of installation package types and perform data insertion on a variety of different file types.

[0036] Furthermore, S4 includes: If the installation type is the first type, the corresponding installation package is the first file, and the personalized data is inserted into the first file according to the first method to obtain the installation package after the data is inserted; If the installation type is the second type, the corresponding installation package is the second file, and the personalized data is inserted into the second file according to the second method to obtain the installation package after the data is inserted; If the installation type is the third type, the corresponding installation package is a third file, and the personalized data is inserted into the third file according to the third method to obtain the installation package after the data is inserted.

[0037] In the above implementation process, personalized data is inserted in different ways according to the installation type, which can avoid the impact of data insertion on the installation package and improve the stability and operation efficiency of the installation package.

[0038] The first type in the embodiment of the present application is the installation of the Windows system, and the corresponding first file is the PE file; the second type is the installation of the macOS system, and the corresponding second file is the PKG file; the third type is the installation of the Xinchuang Tongxin and Kylin desktop system, and the corresponding third file is the DEB file.

[0039] Furthermore, the step of inserting the personalized data into the first file according to the first method to obtain the installation package after the data is inserted includes: Determining whether the first file contains signature information; If so, insert the personalized data into the first file according to the signature information to obtain an installation package after the data is inserted; If not, data insertion fails.

[0040] In the above implementation process, it is determined whether the first file contains signature information, and data insertion processing can be performed on the first file according to its characteristics, which can simplify the data insertion process and improve the stability of the first file.

[0041] The Windows system software installation package is a PE file. The PE file header indicates the location and size of the signature information in the file. This part of the data does not participate in the file hash calculation when verifying the validity of the file signature.

[0042] Therefore, as long as the scope of this area is expanded and the personalized data is inserted after the original signature information, the validity of the signature can be inserted without destroying the data.

[0043] Further, the step of inserting the personalized data into the first file according to the signature information to obtain the installation package after the data is inserted includes: Filling the personalized data into the signature information to obtain a filled first file; Expanding the filled first file to a first threshold file size to obtain an expanded first file; Get the target field in the expanded first file; Verify the target field according to the signature information and obtain the verification result; If the verification result is valid, the target field is overwritten into the file header of the filled first file to obtain the installation package after data insertion.

[0044] In the above implementation process, personalized data is filled into the signature information, and then the filled first file is expanded to determine whether the filled first file can be verified. This can improve the data insertion efficiency of the first file and reduce the risk of data insertion failure.

[0045] Expand the first file after filling to an integer multiple of 8 bytes (the first threshold file size). Only when the size of the first file after filling the signature information remains an integer multiple of 8 bytes can the system recognize the signature information. Otherwise, it will be recognized as having no signature information. Therefore, if the file size is not an integer multiple of 8 bytes after inserting personalized data, it is necessary to continue to expand the data to make up for it.

[0046] Furthermore, the step of verifying the target field according to the signature information includes: Get the signature length in the signature information; Obtaining preset length data according to the signature length and padding length; The length data of the target field is compared with the preset length data. If the length data of the target field is equal to the preset length data, the verification result is valid. If the length data of the target field is not equal to the preset length data, the verification result is invalid.

[0047] In the above implementation process, the preset length data is obtained according to the signature length, and then the preset length is compared with the length data of the target field, which can ensure the rationality and validity of the first file after the data is inserted and improve the availability of the first file.

[0048] There is a field called checksum in the PE file header, which is generated by a verification algorithm. If the value of this field is not equal to the preset length data calculated by the current file, the system will determine that the signature information of the current file is invalid, that is, the verification result is invalid, so this field needs to be recalculated after filling the data.

[0049] Furthermore, the step of inserting the personalized data into the second file according to the second method to obtain the installation package after the data is inserted includes: Determining whether the second file is legal; If so, the structure size of the second file is obtained, the end position of the data heap of the second file is obtained according to the structure size, and the personalized data is inserted into the second file to obtain the installation package after the data is inserted.

[0050] In the above implementation process, it is determined whether the second file is legal, and data is inserted into the second file according to its characteristics, simplifying the data insertion process. At the same time, it is ensured that the inserted data will not damage the structure of the second file, thereby effectively maintaining the stability of the second file.

[0051] The second file consists of three parts: file header, data pile and file tail, among which the file signature only verifies the validity of the contents of the file header and data pile. Therefore, inserting personalized data between the data pile and the end of the file can achieve the insertion of data without destroying the validity of the signature information.

[0052] Furthermore, the step of inserting the personalized data into the third file according to the third method to obtain the installation package after the data is inserted includes: Determine whether the third party document is legal; If so, fill a preset data block at the end of the third file, fill the personalized data into the preset data block, obtain the filled third file, expand the filled third file to the second threshold file size, and obtain the installation package after the data is inserted.

[0053] In the above implementation process, data is inserted according to the file characteristics of the third file, so that the personalized data can be completely inserted into the third file without affecting the installation of the third file, thereby improving the efficiency and security of data insertion.

[0054] The DEB file is an extension of the AR format, consisting of an AR file header and multiple AR data blocks containing the installation compressed package data. The original DEB file is not signed, and the Xinchuang system has made further expansions on this basis, inserting an AR data block (preset data block) containing the file signature at the end of the original file to verify the validity of the AR data block containing the installation package data. Therefore, a new AR data block is inserted into the data packet containing the signature information. At this time, the file size must be an integer multiple of 2 bytes (the second threshold file size), and the personalized information is stored in this preset data block, which can achieve the insertion of data without destroying the validity of the signature information.

[0055] In an embodiment of the present application, an enterprise management software is developed for enterprise administrators to manage all computers installed with management client software from the background. A server is built and provides the enterprise administrator with the function of logging in and downloading the client installation package and viewing the number of clients currently installed in the enterprise.

[0056] Administrators of companies A and B use different corporate accounts to log in to the server, download and install the software from the server, and push it to the computers of their employees for execution.

[0057] The enterprise administrator logs in through the browser and clicks the download installation package button on the front-end page. The server receives the http request for downloading the client installation package initiated by the enterprise administrator from the browser. The server obtains the registration information of the currently logged-in enterprise administrator and inserts some enterprise identification information into the client installation package. The server returns the client installation package to the enterprise administrator, who pushes the installation package to the computers of the employees of the enterprise through other desktop management software and runs it.

[0058] When the installation package is running, it reads the inserted enterprise identification information from its own file and sends a registration request to the server. The server receives the registration request from the installation package, generates the corresponding session cookie and returns it to the installation package. The installation package saves the session cookie to a local file. After the enterprise management software client is installed and started, it automatically reads the cookie saved in the file and communicates with the server. The server associates the current client with the corresponding enterprise through the client's cookie and the enterprise information at the time of registration.

[0059] At this point, the administrator of Company A can associate the employee computers of Company A through the background but cannot manage the employee computers of Company B. The administrator of Company B can associate the employee computers of Company B through the background but cannot manage the employee computers of Company A.

[0060] The embodiment of the present application realizes the function that the same installation package can perceive different user environments and provide users with differentiated experiences through a method of dynamically inserting user personalized information into the installation package based on the server.

[0061] The data insertion method of the embodiment of the present application can perform customized data insertion without destroying the signature information of the original file. When the installation package is running, it parses the inserted data from its own file content and performs different actions according to the data content, thereby realizing the function of providing differentiated experience for different users with the same installation package.

[0062] Embodiment 2 In order to execute the method corresponding to the above embodiment 1 to achieve the corresponding functions and technical effects, a data insertion device for an installation package is provided below, such as Figure 2 As shown, the device comprises: Acquisition module 1, used to obtain the user's download requirements; Extraction module 2, used to extract personalized data in the download request; A selection module 3, used to select an installation type of the installation package according to the installation information in the download requirement; Insertion module 4 is used to insert the personalized data into the corresponding installation package according to the installation type.

[0063] In the above implementation process, different methods are used to insert the user's personalized data into the installation package according to the installation type of the installation package. The customer's personalized information can be inserted into the installation package, so that the installation package can be adaptively adjusted according to customer needs, reducing the deployment difficulty of the installation package, facilitating multiple downloads, and reducing maintenance costs.

[0064] Furthermore, the insertion module 4 is also used for: If the installation type is the first type, the corresponding installation package is the first file, and the personalized data is inserted into the first file according to the first method to obtain the installation package after the data is inserted; If the installation type is the second type, the corresponding installation package is the second file, and the personalized data is inserted into the second file according to the second method to obtain the installation package after the data is inserted; If the installation type is the third type, the corresponding installation package is a third file, and the personalized data is inserted into the third file according to the third method to obtain the installation package after the data is inserted.

[0065] In the above implementation process, personalized data is inserted in different ways according to the installation type, which can avoid the impact of data insertion on the installation package and improve the stability and operation efficiency of the installation package.

[0066] Furthermore, the insertion module 4 is also used for: Determining whether the first file contains signature information; If so, insert the personalized data into the first file according to the signature information to obtain an installation package after the data is inserted; If not, data insertion fails.

[0067] In the above implementation process, it is determined whether the first file contains signature information, and data insertion processing can be performed on the first file according to its characteristics, which can simplify the data insertion process and improve the stability of the first file.

[0068] Furthermore, the insertion module 4 is also used for: Filling the personalized data into the signature information to obtain a filled first file; Expanding the filled first file to a first threshold file size to obtain an expanded first file; Get the target field in the expanded first file; Verify the target field according to the signature information and obtain the verification result; If the verification result is valid, the target field is overwritten into the file header of the filled first file to obtain the installation package after data insertion.

[0069] In the above implementation process, personalized data is filled into the signature information, and then the filled first file is expanded to determine whether the filled first file can be verified. This can improve the data insertion efficiency of the first file and reduce the risk of data insertion failure.

[0070] Furthermore, the insertion module 4 is also used for: Get the signature length in the signature information; Obtaining preset length data according to the signature length and padding length; The length data of the target field is compared with the preset length data. If the length data of the target field is equal to the preset length data, the verification result is valid. If the length data of the target field is not equal to the preset length data, the verification result is invalid.

[0071] In the above implementation process, the preset length data is obtained according to the signature length, and then the preset length is compared with the length data of the target field, which can ensure the rationality and validity of the first file after the data is inserted and improve the availability of the first file.

[0072] Furthermore, the insertion module 4 is also used for: Determining whether the second file is legal; If so, the structure size of the second file is obtained, the end position of the data heap of the second file is obtained according to the structure size, and the personalized data is inserted into the second file to obtain the installation package after the data is inserted.

[0073] In the above implementation process, it is determined whether the second file is legal, and data is inserted into the second file according to its characteristics, simplifying the data insertion process. At the same time, it is ensured that the inserted data will not damage the structure of the second file, thereby effectively maintaining the stability of the second file.

[0074] Furthermore, the insertion module 4 is also used for: Determine whether the third party document is legal; If so, fill a preset data block at the end of the third file, fill the personalized data into the preset data block, obtain the filled third file, expand the filled third file to the second threshold file size, and obtain the installation package after the data is inserted.

[0075] In the above implementation process, data is inserted according to the file characteristics of the third file, so that the personalized data can be completely inserted into the third file without affecting the installation of the third file, thereby improving the efficiency and security of data insertion.
