[0055] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0056] The following describes a program encryption method, device, electronic device, and storage medium according to an embodiment of the present application with reference to the accompanying drawings. First, the program encryption method according to an embodiment of the present application will be described with reference to the accompanying drawings.

[0057] Figure 1 It is a flowchart of a program encryption method according to an embodiment of the present application.

[0058] like Figure 1 As shown, the program encryption method includes the following steps:

[0059] In step S101, the current encryption requirement is obtained.

[0060] The current encryption requirement specifies which source code parts need to be encrypted and which encryption algorithm and key to use. The current encryption requirement can be obtained through a configuration file, command line parameters, or a dedicated interface.

[0061] In step S102, based on the current encryption requirement, source code to be encrypted is determined from preset program source codes, and the source code to be encrypted is encrypted based on the current encryption requirement to obtain the encrypted source code and the encryption identifier corresponding to the encrypted source code.

[0062] That is to say, according to the current encryption requirements, a parser (such as an existing parsing library (ANTLR (Another Tool for Language Recognition, an open source syntax analyzer), etc.)) or a script can be used to read the preset program source code, and by searching for specific functions, classes, string constants, etc., the part of the preset program source code that needs to be encrypted, that is, the source code to be encrypted, is identified. For the determined source code to be encrypted, the selected encryption algorithm can be used to encrypt it, thereby generating an encrypted source code and an encryption identifier corresponding to the encrypted source code.

[0063] For ease of understanding, the following describes in detail how to determine the source code to be encrypted from the preset program source code based on the current encryption requirement.

[0064] As a possible implementation method, in some embodiments, based on the current encryption requirements, the source code to be encrypted is determined from the preset program source code, including: based on the current encryption requirements, determining the position to be encrypted; determining the starting encryption position and the ending encryption position in the preset program source code according to the position to be encrypted; and using the program source code between the starting encryption position and the ending encryption position as the source code to be encrypted.

[0065] Specifically, the position to be encrypted is located according to the current encryption requirements, and then the starting encryption position and the ending encryption position in the preset program source code can be determined according to the position to be encrypted, wherein the starting encryption position is usually the starting position of a specific identifier or pattern, and the ending encryption position can be determined depending on the specific encryption scope and context. It should be noted that for simple string constant encryption, the starting encryption position and the ending encryption position may be the quotation marks of the string. For more complex structures (such as function bodies), it may be necessary to parse the code structure to determine the starting encryption position and the ending encryption position. After determining the starting encryption position and the ending encryption position, the program source code between the starting encryption position and the ending encryption position can be extracted from the preset program source code as the source code to be encrypted.

[0066] After the source code to be encrypted is obtained, the extracted source code fragment to be encrypted can be verified through output or log recording to ensure the accuracy of the source code to be encrypted.

[0067] Further, in some embodiments, the starting encryption position and the ending encryption position in the preset program source code are determined according to the position to be encrypted, including: determining the starting encryption identifier and the ending encryption identifier according to the position to be encrypted; determining the first character position identical to the starting encryption identifier from the preset program source code as the starting encryption position, and determining the last character position identical to the ending encryption identifier from the preset program source code as the ending encryption position.

[0068] Among them, the starting encryption identifier is a specific string or symbol used to mark the starting position of the code segment to be encrypted, and the ending encryption identifier is a specific string or symbol used to mark the ending position of the code segment to be encrypted. These identifiers can be uniquely and clearly identified in the preset program source code and can be pre-set by the user.

[0069] Specifically, by traversing the preset program source code, searching for a character sequence that is exactly the same as the starting encryption identifier, recording the first character position that is exactly the same as the starting encryption identifier as the starting encryption position, and searching for the last character position that is exactly the same as the ending encryption identifier after the starting encryption position as the ending encryption position, ensuring that this position marks the end of the source code segment to be encrypted.

[0070] For ease of understanding, the following describes in detail how to encrypt the source code to be encrypted based on the current encryption requirements to obtain the encrypted source code and the encryption identifier corresponding to the encrypted source code.

[0071] As a possible implementation method, in some embodiments, encrypting the source code to be encrypted based on the current encryption requirement to obtain the encrypted source code and the encryption identifier corresponding to the encrypted source code includes: determining a target encryption strategy according to the current encryption requirement; encrypting the source code to be encrypted according to the target encryption strategy to obtain the encrypted source code, and marking the encrypted source code based on a preset marking strategy to obtain the encryption identifier corresponding to the encrypted source code.

[0072] Specifically, according to the current encryption needs, an appropriate target encryption strategy is analyzed and determined, including encryption algorithms (such as AES (Advanced Encryption Standard)), encryption modes (such as ECB (Electronic Code Book)), and key management strategies, the source code to be encrypted is read from the preset program source code, the source code to be encrypted is encrypted using the selected target encryption strategy, the source code to be encrypted is converted into a byte stream or a text stream, and the encrypted code is encrypted using the selected encryption algorithm. During the encryption process, a key is required to encrypt the source code to be encrypted. After the encryption process is completed, the encrypted data is converted into a source code format to generate an encrypted source code (a format that is unreadable or difficult to directly understand), and the encryption identifier corresponding to the encrypted source code is determined according to the preset marking strategy. The encryption identifier is used to mark the encrypted source code segment.

[0073] In step S103, the encrypted source code replaces the source code to be encrypted, and after the replacement, the replacement position is marked with the encryption identifier corresponding to the encrypted source code.

[0074] That is, in the preset source code, the source code to be encrypted is replaced with the encrypted source code, and an encryption mark corresponding to the encrypted source code is added at the replaced position to mark that the position has been encrypted, such as by adding comments, modifying the code style or using specific metadata tags.

[0075] Furthermore, in some embodiments, after replacing the source code to be encrypted with the encrypted source code and marking the replacement position with the encryption identifier corresponding to the encrypted source code after the replacement, it also includes: judging whether a decryption request from the user is received; if a decryption request from the user is received, obtaining the identity information of the user, and judging whether the user is in a preset decryption personnel library according to the identity information; if the user is in the preset decryption personnel library, determining the position to be decrypted based on the encryption identifier corresponding to the encrypted source code, and decrypting the encrypted source code according to the position to be decrypted to obtain the source code to be encrypted.

[0076] Specifically, after encrypting the source code to be encrypted in the preset program source code, the system can continuously monitor whether there is a user's decryption demand through a user interface, an API (Application Programming Interface) call, etc. Once the user's decryption demand is received, the validity of the demand needs to be determined. If the decryption demand is valid, the user identity information (including user name, password, access token, etc.) requesting decryption can be obtained, and the user's identity information can be compared with the preset decryption personnel library to confirm whether the user has the right to perform the decryption operation. If the user identity information exists in the preset decryption personnel library, the system determines that the user has the right to decrypt, and then finds the encryption identifier corresponding to the encrypted source code by searching for a specific mark or identifier to determine the position to be decrypted. According to the encryption position, its starting encryption position and the ending encryption position can be determined, so as to locate the encrypted source code, retrieve the key and encryption algorithm information associated with the position from the preset encryption personnel library, and use this information to decrypt the encrypted source code, and restore the encrypted source code to the original source code to be encrypted. After decryption is completed, the decrypted source code to be encrypted can be replaced back to the corresponding position in the preset program source code.

[0077] Optionally, in some embodiments, after determining whether the user is in a preset decryption personnel database based on the identity information, the method further includes: if the user is not in the preset decryption personnel database, sending a decryption failure message to a preset mobile terminal.

[0078] It is understandable that if the user is not in the preset decryption personnel database, the system will reject the decryption request, indicating that the user does not have decryption authority, and generate corresponding decryption failure information (including error code and description so that the user can understand the reason for the failure to decrypt), and send the decryption failure information to the preset mobile terminal (such as mobile phone, tablet computer, etc.) associated with the user in an appropriate manner (such as SMS, push notification, email, etc.). After receiving the decryption failure information, the user can understand the reason according to the failure information and take appropriate actions, such as contacting the administrator, checking his own authority, etc.

[0079] According to the program encryption method proposed in the embodiment of the present application, based on the current encryption requirements, the source code to be encrypted can be determined from the preset program source code, and the source code to be encrypted can be encrypted based on the current encryption requirements to obtain the encrypted source code and the encryption identifier corresponding to the encrypted source code; the encrypted source code is replaced with the source code to be encrypted, and the replacement position is marked with the encryption identifier corresponding to the encrypted source code after the replacement. Thus, the problem that the source code obtained after the source code is obfuscated in the prior art is difficult to understand and the obfuscated source code is difficult to debug is solved, and the confidentiality of the source code is improved.

[0080] Next, the program encryption device proposed according to the embodiment of the present application is described with reference to the accompanying drawings.

[0099] The decryption unit is used to determine the position to be decrypted based on the encryption identifier corresponding to the encrypted source code when the user is in the preset decryption personnel database, and decrypt the encrypted source code according to the position to be decrypted to obtain the source code to be encrypted.

[0101] When the user is not in the preset decryption personnel database, a decryption failure message is sent to the preset mobile terminal.
