3des key generator

3DES encryption has different encryption mode and fill mode, this online a lot of said, as long as the encryption mode and the filling mode to ensure that the decryption is consistent with the first for the key generation, there are 2 ways in Java: 1

3DES, or Triple DES, is the enhanced version of Des and also a more secure variant of DES. It uses 3 56-bit (168-bit) keys to encrypt the data three times, and compared to DES, the security has been greatly improved.In fact, 3DES is a transition
