如何给一个自己定义的字符串进行3DES加密？

Question

要怎么做呢，是自己定义的24个字节的字符串，求大神指教啊。。

试试这样：

 final byte[] keyBytes = {0x11, 0x22, 0x4F, 0x58, (byte)0x88, 0x10, 0x40, 0x38
                               , 0x28, 0x25, 0x79, 0x51, (byte)0xCB, (byte)0xDD, 0x55, 0x66
                               , 0x77, 0x29, 0x74, (byte)0x98, 0x30, 0x40, 0x36, (byte)0xE2};    //24字节的密钥
String szSrc = "This is a 3DES test. 测试";
ThreeDes t = new ThreeDes();
byte[] encoded = t.encryptMode(keyBytes, szSrc.getBytes());
System.out.println("加密后的字符串:" + new String(encoded));
