经典的文件加密技术，简单高效

这个是RSA密钥对生成器，使用RSA EURO-This is the RSA key pair generator, the use of RSA EURO

时域LSB隐藏算法,实现随机信息隐藏到载体图片内,并界附带提取信息代码-LSB hidden time-domain algorithm, the realization of random information hidden within the picture carrier, and industry code attached to extract information

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!
