WPF将用户名和密码加密保存在文件当中,非常好的资料(WPF user names and passwords encrypted and stored in a file which is very good information)

对称加密（DES加密解密），非对称加密（RSA加密解密）。(Symmetric encryption (DES encryption and decryption), asymmetric encryption (RSA encryption and decryption).)

RC3算法，用c语言实现。包括加密和解密(The RC3 algorithm using the C language. Including encryption and decryption)

sha256计算代码，非常好用的代码，大家可以用这个代码直接计算哈希值，sha256实现 依次执行 SHA256Init、 SHA256Update SHA256Final 三个函数即可得到sha256结果(sha256 sourse code，Is very usefull)

基本古典密码设计——周期为3的多表代替密码的设计和实现(Basic classical cipher design)

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.)

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.)
