aes 256 encryption algorithm

Objective: In front of the study summed up the usual development encountered in various data encryption methods, the end will be encrypted binary data Base64 encoding, play a two times the effect of encryption, in fact, Base64 from the strict sense is not a cryptographic algorithm, but a coding algorithm, Why use

RSA algorithm C # implemented based on private key encryption and Public Key decryption, The RSA algorithm is the first algorithm that can be used for both encryption and digital signature, and is easy to understand and operate. RSA is the most widely studied public key

The security of e-commerce is becoming more and more prominent because of the great security risk of the information transmission on the Internet. Encryption is the most important security technology in E-commerce, the choice of encryption method directly affects the degree of information security in e-commerce activities, in E-commerce syst

Symmetric encryption algorithm is an early application of encryption algorithm, the technology is mature. In the symmetric encryption algorithm, the sender of the data sends the plaintext (raw data) and the
