Des symmetric encryption Algorithm Invalid key Length:8 bytes

Security.addprovider (New Com.sun.crypto.provider.SunJCE ());
Key key = new Secretkeyspec (Secretkey.getbytes (), "DES");

Encryptcipher = Cipher.getinstance ("DES");
Encryptcipher.init (Cipher.encrypt_mode, key); 8 key strings, and3DES is a minimum of 16 key strings. this is the key. Basic idea: The signing number after the 10-bit +YYMMDD 16-bit as the DES key, generate the key is 8 key strings.
