Understanding 3DES Encryption Algorithm

Understanding 3DES Encryption Algorithm

3DES is the common name for the Triple Data Encryption Standard. It is an enhanced version of the DES algorithm, equivalent to applying the DES operation three times to each data block. Due to the increased key length, the security level and difficulty of cracking are higher than that of the DES algorithm. The encryption … Read more
