Abstract

The embodiment of the invention provides a file encryption method and device, electronic equipment and a storage medium, and relates to the technical field of file protection. The method comprises the following steps: extracting constants defined in an archived file of the SDK; encrypting the constant according to a preset encryption algorithm; and replacing a definition instruction for the constant in the archived file with a pre-generated calling instruction of the decryption module, and taking the encrypted constant as a parameter transmitted to the decryption module when the decryption module is called, wherein the decryption module is located in the SDK and is used for decrypting the received parameters according to a decryption algorithm corresponding to a preset encryption algorithm. The constant definition in the SDK is replaced by the decryption module calling instruction, and the constant is not exposed in the SDK in a plaintext mode any more, so that the risk of constant plaintext exposure is avoided, and the safety performance is improved. When the constant of the SDK is called, the decryption module is actually called, and the decryption module decrypts the encrypted constant and outputs the decrypted constant, so that the normal use of the SDK is not influenced.

Description

technical field [0001] The invention relates to the technical field of file protection, in particular to a file encryption method, device, electronic equipment and storage medium. Background technique [0002] In the SDK (Software Development Kit, software development kit), some important information such as keys, text prompts, and configuration item names are often stored in the code as constants, and there is a risk of plaintext exposure. Crackers only need to statically analyze the SDK file to find these constant information, or use a Find command (find command) in the prompt text to locate the key code location and view the exposed plaintext information, which has poor security performance. Contents of the invention [0003] The present invention provides a file encryption method, device, electronic equipment and storage medium, which solves the problems in the prior art that the constants in the SDK have the risk of plaintext exposure and poor security performance. ...
