转下的源代码程序,此程序需要密码,但可以正常使用,并可对后台进行部分修改(Transfer the source code under the program, this program requires a password, but can be used normally, it may also be part of the background changes)

RSA加密算法，实现对文字的加密，将文字转化成数字后用RSA原理进行加密(This is RSA encryption algorithm)

一个静态反汇编工具，也是破解人常用的工具之一(W32Dasm is a static disassembly tool, but also break one of the tools were used)

Themida的另类破解 附件提供的一个程序是用汇编写的PE信息小工具，用Themida1855加密，加密选择RISC-64 processor，全选加密可选项，并对部分API函数使用VM加密，入口虚拟系数选择15。

说明：  一个关于加密音频，图像的VB程序，功能还算可以，希望可以帮到人！！(One on encryption of audio, images VB program, function OK, the desire to help people! !)

SHA-256源代码，三个对外的函数：void SHA256Init (SHA256Context *sc) void SHA256Update (SHA256Context *sc, const void *data, uint32_t len) void SHA256Final (SHA256Context *sc, uint8_t hash[SHA256_HASH_SIZE]) 第一个函数初始化，第二个函数输入要hash的字符串，第三个函数输出结果(SHA-256 source code, three external function: void SHA256Init (SHA256Context* sc) void SHA256Update (SHA256Context* sc, const void* data, uint32_t len) void SHA256Final (SHA256Context* sc, uint8_t hash [SHA256_HASH_SIZE]) The first function is initialized, the second hash function, enter the string, the third function of output)

md5及sha-1算法及验证文件，vc6.0调试无误(md5 and sha-1 algorithm and verification documents, vc6.0 debug and correct)

1、 所有密钥的装载与导出都采用密文方式； 2、 密钥管理系统采用3DES加密算法，采用根密钥生成系统、主密钥生成系统、初始化卡生成系统、密钥注入系统四级管理体制； 3、 在充分保证密钥安全的基础上，支持IC卡密钥的生成、注入、导出、备份、更新、服务等功能，实现密钥的安全管理； (1, the loading and export all keys are in cipher text 2, the key management system uses the 3DES encryption algorithm, using the root key generation system, the master key generation system, initialize the card generation system, key injection system four management systems 3, the key to ensure full security, based on the support of the IC card key generation, injection, export, backup, update, and service functions to achieve key security management )

以DES加密算法为例理解对称密码算法，用计算机模拟DES加密解密算法。 (DES encryption algorithm as an example to understand the symmetric cipher algorithm, using computer simulation DES encryption and decryption algorithms.)

OpenSSL的RSA算法应用举例。是用VC写的，有实用价值。(RSA algorithm of OpenSSL is used and given an example. Written with VC, there is practical value. )
