RSA C语言实现

关于数字水印嵌入时处理水印的源代码，采用猫脸变换对水印图像进行预处理 -Be dealt with on the digital watermark embedding watermark source code, using a cat face on the watermark image pre-processing transformation

这个是简单的用vb编程编的分解质因数的程序和已经编译了的exe文件-This is a simple program with vb series of the quality factor of the decomposition process and is compiled by the exe files

1.本程序将所有可能出现的英文和符号定义在ASCII表中的“000--255”中的256个常用字符 2.在实现2的基础上，实现控制台对英文文本文件（注意明文和密文都以文件形式存在）的加解密 形式：cipher 源文件名 目的文件名 密钥 E/D（标示加解密）说明：对于加密来说，源文件名就是明文，对于解密来说，源文件名就是密文-1. This program will all possible symbols in English and in the definition of the ASCII table, "000-- 2 55 "of 256 commonly used characters in two. in achieving two on the basis of Console achieve the English text files (and expressly close attention to the text of a document form) encryption forms : cipher source document file names Key E/D (marked increase declassified) Note : For encryption, source file name is expressly for declassification, the source file name is ciphertext

用JAVA做的模拟电梯的程序,是自己做的- Simulation elevator procedure does which with JAVA, is oneself does

应用背景 跨平台的DES及3DES算法源程序,标准C实现，可用于unix/linux/windows平台。 -DES and 3DES algorithm source code, the standard C implementation, which can be used for unix/linux/windows platform. 关键技术 DES:   密钥:   0x67, 0xBE, 0x03, 0x7C, 0x41, 0x96, 0x6D, 0xDB   明文:   0xA9, 0x37, 0x07, 0x49, 0xFC, 0x06, 0xAF, 0xE6   密文:   0x60, 0x78, 0x32, 0xE8, 0xB3, 0x5A, 0x9C, 0x6D DES3:   密钥:   0x40, 0xbb, 0x12, 0xdd, 0x6a, 0x82, 0x73, 0x86,   0x7f, 0x35, 0x29, 0xd3, 0x54, 0xb4, 0xa0, 0x26,   0x40, 0xbb, 0x12, 0xdd, 0x6a, 0x82, 0x73, 0x86   明文:   0x49, 0x07, 0x37, 0xa9, 0xe6, 0xaf, 0x06, 0xfc   密文:   0x43, 0x01, 0xc5, 0x6b, 0x14, 0x00, 0xe7, 0xce   

以前发的那个只实现了SHA-1, 现在补全了, sha-160, sha-224, sha-256, sha-384, sha-512-Previously issued only to realize that the SHA-1, is now a complete, sha-160, sha-224, sha-256, sha-384, sha-512
