Chilkat Java Encryption Library

The Chilkat Java encryption library gives an advanced API for symmetric encryption, public-key encryption, digital signatures, hashing, and encoding/decoding. The Chilkat items and libraries have an established user base of approximately 10,000 customers. The licensing gives for free new-version upgrades, 1 year unlimited email and phone support, and royalty-free redistribution.
