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)

仿射密码体制加解密，较移位代换等加解密体制，更加优越。(Affine cipher encryption and decryption, a shift substitution and encryption and decryption system, more superior.)

AES128bit加密算法。在PDF文档中有详细算法描述(AES128bit encryption algorithm. PDF documents are detailed in the algorithm description)

该文件能用Visual C++6.0打开编译实现加密解密功能，并能通过少量的修改改(修改处程序源码中已标明)镶嵌到其他的程序源码中实现加密解密功能。 可直接使用。 (The file can use Visual C++6.0 to open compiled encryption and decryption functions through a few modifications reform (modify at program source code has been marked) inlaid into the other program source code to achieve encryption and decryption functions. Can be used directly.)

一个用vc编写的aes算法实现，含有128，192，256三种钥匙长度的(a prepared using vc Orangk'aes algorithm, containing 128,192,256 length of the three key)

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.)

修改本程序中的U盘的序列号后，程序可以变成你自己的独立的Ｕ盘启动密匙，　只能你的Ｕ盘才能打开程序　不需要往Ｕ盘中存入任何文件，就可实现用Ｕ盘加密程序.只能通过你的U盘启动你的程序 程序中有详细的注释(Encrypt your program by a soul U-disk without saving anything in you disk Modify the program, U-disk serial number, the program can become your own independent U disk key, only you can open U disk U disk does not need to deposit any file, can be achieved U disk encryption program)

文件加密使用,可以实现对PC上文件进行加密解密功能(document encryption use, the PC can be achieved on the document encryption and decryption functions)

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)

基于crypto++实现RSA密钥对生成，密钥长度1024，vs2010实现(generate RSA key pair based on Crypto++，and save the key pairs which is 1024 bit in txt file )
