一款和不错的用VC实现的DES算法,希望对大家对提意见,-section and a good VC with the DES algorithm, we hope that the right to say,

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!

 What is EAQUAL?     The intention of EAQUAL is to provide a objective quality measure for coded/ decoded audio      files. Currently the code is based on the ITU-R recommendation BS.1387.      EAQUAL will not supersede listening tests, but can be a useful tool to support listening tests,      categorize different coding algorithms and find bugs in algorithms. The more input files are      taken for the analysis, the better the results of EAQUAL will fit the reality.
