WebThis is the successor to DES. NIST wanted a block cipher using symmetric key cryptography, and had a handful of options. They went with the Rijndael option, which has three different standard key sizes (AES-128, AES-192, and AES256). It’s secure and computationally efficient. RC4 “RC” stands for Rivest Cipher, as Ron Rivest designed them. WebRC4 is a symmetric, stream cipher, and uses a series of swap, add, modulus, and exclusive-OR operations to perform its encryption.
