AES and DES need IV parameter IVPARAMETERSPEC IV = new Ivparameterspec (Key.getbytes ()) in CBC operation mode. Encryption Cipher.init (Cipher.encrypt_mode, Secretkey, iv); Summarize DES security is not high enough in modern times, then the 3DES algorithm has been improved a lot, but its implementation efficiency is low, AES algorithm encryption strength, high execution efficiency, simple to use, the actual development of the propose
