It encrypts blocks of data in three stages using a 168-bit key length. It is an encryption standard that uses keys that are 448 bits in length. It is a fast encryption standard that operates on streams of data instead of blocks of data and uses variable length keys up to 2048 bits in length. It is an improvement on the 3DES encryption method and is available in 128, 192, and 256 bit key lengths. It is an improvement on the 3DES encryption method and is available in 128, 192, and 256 bit key lengths.
