what is rsa and aes ciphers
As first publicly accessible, from the NSA for the classification top secret approved cipher, the Advanced Encryption Standard (AES) is one of the most frequently used and most secure encryption algorithms available today.
1 Usually RSA is used to share a secret key and then a symmetric key algorithm is used for the actual encryption. 2  RSA can be used for digital signing but is slower. 3  DSA (see below) is preferred. 4  However, RSA signatures are faster to verify.
