WebMar 9, 2016 · HMAC-SHA1 is not an encryption algorithm. It is a hashing function. Wikipedia and other sources are good at explaining what AES, HMAC, and SHA-1 are. In all honestly, you shouldn't be rolling your own crypto and if you know this little about crypto you probably shouldn't be developing this part of the application at all. WebApr 12, 2024 · The Advanced Encryption Standard (AES) is a symmetric block cipher that's used for classified information by the U.S. government. Development of AES began in 1997 by NIST in response to the need for an alternative to the Data Encryption Standard (DES, discussed below) due to its vulnerability to brute-force attacks.
