信息加密原码，用md5算法实现，开发语言：c(original message encryption code used md5 algorithm, the development of language : c)

该程序使用C++写的一个基于递归子程序算法的语法翻译器，是在vs2012环境下编写的，供大家参考和学习(The program uses C++ to write an algorithm based on recursive subroutine syntax interpreter is written in vs2012 environment, for your reference and learning)

基于RSA算法的加密解密以及数字签名系统，实现加密解密签名的功能(RSA-based encryption and decryption algorithms and digital signature system to achieve the function of signature encryption and decryption )

RSA加密算法的C预言实现，对一张灰度图进行加密，然后再解密(RSA encryption algorithm in C prophecy fulfilled, encrypt and then decrypt a grayscale)

windows登陆密码信息拦截，获取明文口令。程序对不同系统做了处理，在2000,2003,xp,vista上都可以截取， 在2000,2003,xp中，通过UNICODE_STRING.Length 的高8位取xor key,如果密码是编码过的，则通过ntdll.RtlRunDecodeUnicodeString解码， vista则通过AdvApi32.CredIsProtectedW判断密码是否编码过，解码用AdvApi32.CredUnprotectW。(The windows Password intercept, access to the plaintext password. Processing program on a different system in 2000, 2003, xp, vista can intercept, 2000,2003, xp UNICODE_STRING.Length high eight take xor key if the password is encoded by the ntdll.RtlRunDecodeUnicodeString decoding, vista, to judge by AdvApi32.CredIsProtectedW and password whether encoding, decoding AdvApi32.CredUnprotectW.)

加密算法RSA，DSA等，用C++实现，内附加有详细的说明(Encryption algorithm RSA, DSA, etc., using C++ Realize, with additional detail has)

说明：  密码学BM算法的C++实现。可计算100阶m序列的生成多项式(Cryptography BM algorithm in C++. Computable 100 m sequence generator polynomial order)

身份证15位转18位的算法原码，可以自动将转换后的结果放入剪贴板中(Algorithm of the original code ID card 15 turn 18, you can automatically converted into the clipboard)

pdf文件加密移除小软件。使pdf文件可打印可注释。(To remove pdf file encryption. So files can be printed comments)

检测CRC编码 看CRC编码在传输后是否有错误 有变动 (Detection CRC codes to see whether the CRC coding errors in the transmission there is a change)
