Abstract

The embodiment of the invention discloses a file encryption and decryption method and device, a processing terminal and a computer readable storage medium. The encryption method comprises the steps that a plaintext configuration item under a server environment is obtained; if the plaintext configuration item comprises sensitive information, a latest recognition prefix and an encryption key in an encryption key table are obtained; the plaintext configuration item is encrypted according to the encryption key and an AES encryption algorithm, and encryption ciphertext is obtained; according to theencryption ciphertext and the latest recognition prefix, the encryption configuration item is obtained. Accordingly, in the encryption process, the encryption item is flexibly configured according tothe encryption key table, and the user requirements are met; in the decryption process, the decryption process is implemented rapidly and easily according to the encryption key table.

Description

technical field [0001] The technical field of data processing of the present invention specifically relates to a file encryption and decryption method, device, processing terminal and computer-readable storage medium. Background technique [0002] Sensitive information such as user names and passwords will inevitably be contained in configuration files in the server environment, and the confidentiality of such information plays a vital role in the security of the entire server. Therefore, in order to prevent similar sensitive information leakage, the configuration file needs to be encrypted. [0003] The existing file encryption method uses a built-in fixed key to encrypt specific configuration item names, but this method cannot configure encrypted items flexibly and cannot meet user needs. Further, the existing file decryption method is too complicated. Contents of the invention [0004] An object of the embodiments of the present invention is to provide a file encrypti...
