傅里叶快速算法，DLL可有其他程序调用很好的呀，免费下载，不需账号即可。多多支持。-Fast Fourier algorithm, DLL can call other procedures are very good ah, the free download, can not account. For their support.

Software for Low Density Parity Check Codes Radford M. Neal Version of 2006-02-08. This collection of programs and modules, written in C, is intended to support research and education concerning Low Density Parity Check (LDPC) codes. (Note, however,

用C++简单地实现了AES算法，可以实现128bits的字符串加密、解密，密码为128bits，具有很好的扩展性，可很容易地扩展为文件加密-Simply achieved with C AES algorithm, can achieve 128bits string encryption, decryption, password is 128bits, with good Scalability can be easily extended to file encryption
