Lava's jDES is a highly optimized, highly configurable implementation of the Data Encryption Standard (DES) in Java. jDES was designed with four goals in mind:
jDES utilizes Sharkysoft's proprietary reformulation of DES optimized for 32-bit machines. Tests have shown that jDES can outperform the JCE (Sun's cryptography library) in DES computations by as much as 25%.
