The system realizes the introduction of cryptography knowledge, and the demonstration of the DES algorithm, RSA algorithm, shift substitution algorithm, permutation cipher algorithm, MD5 algorithm and so on for encryption and decryption. The test and application results show that the system has the encryption and decryption function of the commonly used encryption algorithms, which has certain help and reference value for the study of course and related content.
