摘要：Disclosed is a method for implementing an encryption engine, which includes: when an engine binding interface is called, a hardware encryption engine establishes a connection with a hardware encryption equipment, acquires an algorithm list of said hardware encryption equipment, and fills a first data structure; when a key initialization interface is called, said hardware encryption engine, according to the transmitted first data structure, sets an encryption/decryption algorithm to be used by said hardware encryption equipment, and retrieves a corresponding algorithm key; and if no algorithm key is retrieved, said hardware encryption engine controls said hardware encryption equipment to create said algorithm key; when a data encryption/decryption interface is called, said hardware encryption engine, according to the currently set encryption/decryption algorithm and said algorithm key, controls said hardware encryption equipment to perform an encryption/decryption operation on the transmitted data, and outputs the operation result; and when an engine release interface is called, said hardware encryption engine ends the connection with said hardware encryption equipment. The present invention can add or extend the encryption/decryption algorithm that can only be implemented in hardware to a software algorithm library.
