I found today a Java package, implementing some cryptography (MD5, DES, RSA and Diffie-Hellman). Seems quite interesting. It is called JCrypt alpha release 0.1. The information is on: http://www.cs.utexas.edu/users/achou/JCrypt/packages.html Sorry if this has been on this list already. Jüri Kaljundi jk at digit.ee Digiturg http://www.digit.ee/
