It was designed by Bruce Schneier, John Kesley, Dough Whiting, David Wagner, Chris Hall and Niels Ferguson. Twofish algorithm is successor of blowfish algorithm. But presently Triple DES is largely replaced by AES (Advance Encryption Standard). Triple DES is well suited for hardware implementation. However Triple DES suffers from slow performance in software. It has a key length of 168 bits three 56-bit DES keys but due to meet-in-middle-attack the effective security is only provided for only 112 bits. In 1956 it was found out that 56 key-bit of DES was not enough to prevent brute force attack, so Triple DES was discovered with the purpose of enlarging the key space without any requirement to change algorithm. Triple DES: Triple DES is a block cipher algorithm that was created to replace its older version Data Encryption Standard(DES).There are four such encryption algorithms that are highly secured and are unbreakable. Presently there are many options to choose and find out the most secure algorithm which meets our requirements. It helps in protecting consumer information, emails and other sensitive data from unauthorized access to it as well as secures communication networks. The algorithm that is used for the process of encryption is known as cipher.
