Problems solved by technology
For example, if a third party manages to obtain the author's private key without the author's knowledge or authorization, the third party may sign and distribute the application, thereby maliciously replacing the author's original application or damaging them
In addition, a third party who obtains the private key can also use the identity of the author to sign and distribute the application, thereby attacking other applications or the system itself, damaging or stealing user data
[0004] At present, most of the application signature work is done by the author on the local client, which can easily cause the leakage of the private key. Therefore, a more secure application signature scheme is needed

The invention discloses an application signature method, device, system, computing equipment and storage medium. In response to receiving the application signature request for the target application sent by the client, it is checked whether there is a signature file corresponding to the target application in the signature file database. If found, send the signature file to the client. If it cannot be found, use the preset private key to generate a signature file for the target application, save the generated signature file in the signature file database, and send it to the client. Therefore, by handing over the signing work of the application to the server side, the risk of private key leakage during the application signing process can be reduced, and the security of the signing process can be improved.
Description
technical field [0001] The present invention relates to the field of application signatures, in particular to an application signature method, device, system, computing equipment and storage medium. Background technique [0002] Application signature means that after the application development or update is completed, the application file is digitally signed with the private key to obtain the signature file. A trust relationship can be established between the author of the application and the application by signing the file. [0003] The software installation package of the application is only allowed to be put on the market or installed in the terminal device after being signed. Therefore, maintaining the security of the private key is of paramount importance to the author of the application. If the signature private key is leaked and obtained and used by a third party, it will damage the authorship of the application and the user's trust in the author. For example, if a...
