简单的文件加密代码 一个不错的文件加密系统，对你工作的安全大大加强。-simple file encryption code a good file encryption system, you have the right security greatly enhanced.

关于IDEA算法的一个小程序-IDEA algorithm on a small program

这是很好的源代码，对于很多的童鞋来说是非常好的资料，而且程序简单易懂。本程序是在VISUAL C++6.0运行，不过在其他版本的软件上应该也可以运行。

利用Rijndael算法进行任意文件的加密。把任意一个文件分成N个16字节组，最后一组若不足16字节可以用空格去补！-Rijndael algorithm using arbitrary file encryption. To arbitrary N of a document is divided into 16-byte groups, and finally a group of less than 16 bytes can be used to fill space!

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.
