Detailed Description

TripleDES Algorithm Encryptor/Decryptor

TripleDES, TDEA or 3DES, is multiple applications of the DES algorithm to plain text data to increase the security of the original DES algorithm.As the name implies, the DES algorithm is applied 3 times.There are two variants of TripleDES : the first is two key;and the second is three key. 2 - key TDEA provides approximately 80 bits of security, while 3 - key TDEA provides approximately 112 bits of security.In contrast, AES provides a minimum security level of 128.
