I am looking for suggestions for features to include in the next version of Crypto++ (current version is 1.1, you can find it at http://www.eskimo.com/~weidai/cryptlib.html). Major additions already planned/implemented include speed improvements, Safer (all the variations), and elliptic curve cryptosystems (over prime fields as well as fields of characteristic 2). There is also a good chance that RSA will be added back, but I'm still waiting for the final word from the RSADSI lawyer. What else do people want to see? Wei Dai
