There are two series of encryption algorithms, symmetry-key and public-key encryption algorithm. According to user¡¯s choice and demand, choice of algorithm is different. And an implementation of a algorithm using improper parameter can also bring you security problem , even it is a secure algorithm.
Antiy Labs have released an algorithm library BNT&CAL SDK by sep,2000. It includes more than 30 popular algorithms: DES (including great improvement), IDEA, RSA, DSA, DH/DSS, MD4, MD5, etc. And ellipse-curve algorithm in F(2^m) and F(p) is also included. The implementations of these algorithms avoid known security problem, and are improved in efficiency. It is better than other products in security and speed. It is developed in standard c++, and can be compiled with VC and GCC without any change.
