RSA is an asymmetric encryption algorithm that uses public and private keys for encryption and decryption. It was created in 1978 but is slower than the symmetric AES algorithm, which uses a single key for encryption and decryption and was created in 2001. While RSA provides variable size encryption and keys, AES operates faster through multiple rounds and stages on 128-bit blocks.
