Android, iphone and Java three platform consistent encryption tools

Having previously been an Android, and recently developing an iphone client, the most troubling of all is the inconsistency between the Java, Android and iphone three platforms plus decryption. Because the end of the phone is usually the Java-developed web service,android and iphone clients invoke the same Web Service interface, for data security considerations, to encrypt the data. The headaches are coming, it's hard to write a set of encryption programs, the results are consistent between 3 platforms, and you can't always write a Web service interface for Android and iphone two clients. I'm sure there will be a lot of friends out there, sharing a set of 3DES encryption programs that will allow Java, Android and iphone three platforms to be decrypted.

The first is the Java side of the encryption tool class, it also applies to the Android side, without any modification, you can ensure that Java and the Android side of the encryption and decryption consistent, and Chinese will not garbled.
