WebApr 5, 2011 · AES is a symmetric cryptographic algorithm, while RSA is an asymmetric (or public key) cryptographic algorithm. Encryption and decryption is done with a single key in AES, while you use separate keys (public and private keys) in RSA. The strength of a 128-bit AES key is roughly equivalent to 2600-bits RSA key. WebAdvanced Encryption Standard is the most widely used algorithm in symmetric key cryptography. AES was named successor to DES by NIST in 2001. AES comprises three block ciphers -- AES-129, AES-192 and AES-256 -- each of which is deemed sufficient to protect government-classified information up to the Secret level, with Top Secret …
