Encryption and decryption module control method

The invention discloses an encryption and decryption module control method, belongs to the technical field of encryption and decryption modules, and aims to solve the problems that the existing overall security is relatively low, the control authority of the encryption and decryption module is easy to open, and if a disconnection phenomenon occurs, a password is also lost. The method comprises the following steps: 1) identity authentication; 2) setting an initial password; 3) storing and uploading the password; 4) later decryption; and 5) risk maintenance: five implementation steps are carried out. According to the invention, the cloud storage library is established, the cloud storage library and the encryption and decryption module are connected through the same local area network, the established various types of passwords are stored and uploaded to the cloud storage library through the local area network, and the passwords are verified and compared with the originally established initial passwords in the u
