MD5VB2010实现MD5加密，计算机VB程序(MD5VB2010 achieve MD5 encryption, computer VB program)

RSA算法，主要讲述算法的原理和过程，设计到加密解密，和溢出处理，初级学习RSA用(RSA algorithm, the algorithm mainly about the principle and process design to the encryption and decryption, and overflow processing, the primary study used RSA)

playfair 加密算法的实现，用一个例子做了展示(realize playfair algorithm，use a sample to show the algorithm)

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.)
