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.)

VB文件加密器（异或加密）,有需要的就下载吧。(VB file encryption (XOR encryption), there is a need to download it.)

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)

实现维吉尼亚密码，用键盘接收明文和密钥，屏幕打印密文和解密后的明文。 可以实现：大小写敏感，明文小写则密文大写，明文大写则密文小写输出，注意输入的健壮性控制，明文字符超出字符集后保留原文(Virginia to achieve the password, use the keyboard to receive the plaintext and the key, the screen printing ciphertext and the decrypted plaintext. Can be achieved: case sensitive, then the ciphertext plaintext lowercase uppercase, lowercase plaintext ciphertext output is capital, pay attention to the robustness of the control input, plaintext characters out retain the original character set)

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)

实现对单文件的DES加密解密，不限制大小，DES加密部分自写，非调用，用于学习DES原理。(The realization of the single document DES encryption and decryption, no limit to the size, DES encryption part self written, non call, for learning DES principle.)

文件的加密传输，用到了各种加密算法 MD5 RSA (File encryption MD5 RSA )

密码技术实验一经典密码学实验维多利亚密码加密解密(Password technological experiments classic cryptography experimental Victoria password encryption and decryption)

文件系统过滤驱动程序的框架，对于做文件透明加密的朋友很有帮助()
