In the previous article, I introduced some important classes of the enterprise database cryptographer module, and introduced the extended interfaces provided by the enterprise database cryptographer module. Today I will perform extended development

Encryption and decryption use the same key algorithm, called symmetric encryption algorithm. encryption and decryption use different keys, called asymmetric encryption algorithms. The public key system is an asymmetric encryption algorithm. For
