* 使用DES加密与解密,可对byte[],String类型进行加密与解密 密文可使用String,byte[]存储.

*

* 方法: void getKey(String strKey)从strKey的字条生成一个Key

*

* String getEncString(String strMing)对strMing进行加密,返回String密文 String

* getDesString(String strMi)对strMin进行解密,返回String明文

*

*byte[] getEncCode(byte[] byteS)byte[]型的加密 byte[] getDesCode(byte[]

* byteD)byte[]型的解密-* The use of DES encryption and decryption, can be byte [], String type ciphertext encryption and decryption can use String, byte [] storage.** Method: void getKey (String strKey) note from strKey generate a Key** String getEncString (String strMing) to encrypt strMing, String ciphertext return String* getDesString (String strMi) to decrypt strMin, return String expressly** byte [] getEncCode (byte [] byteS) byte [] encryption type byte [] getDesCode (byte []* byteD) byte [] type of decryption
