C++写的椭圆曲线加密算法库源码-source code of ECC in C++

libGringotts是一个小型、易于使用的、完全线程的C语言库，最初为Gringotts开发。它的目的是将数据封闭在一个加密和压缩的文件中。它使用加密算法（(RIJNDAEL 128/256, SERPENT, TWOFISH, CAST256, SAFER+, LOKI97, 用于加密的3DES, 以及哈希函数的SHA1和 RIPEMD-160)来确保数据尽可能安全，并允许用户对所有使用的加密、哈希函数和压缩算法有完全的控制。 -libGringotts is small, is easy to use, the entire line regulation C language storehouse, at first is the Gringotts development. Its goal is the data seal in an encryption and in the compression document. It uses the encryption algorithm ((RIJNDAEL 12.8/256, million SERPENT, TWOFISH, CAST256, SAFER, LOKI97, uses in 3DES which encrypts, as well as Hasche function SHA1 and RIPEMD-160) guarantee the data to be as far as possible safe, and the permission user to all uses encryption, the Hasche function and the compression algorithm has the complete control.
