DESEncryptionDecrypt

文件加密器,实现对文件加密,用来学习的代码(File encryption, encrypting files, the code used to study)

本文使用ECC加密AES的密钥，再由AES加密明文内容，AES加密强度大，速度快，但是密钥更新繁琐和不安全，由强度很大的非对称密钥算法对AES密钥加密，结合了两方的优点(this programme combine the ECC with AES.using the ECC to cipher the AES key,and using the AES to cipher the m)

rockey6加密狗 dogsn名称为3000(dogsn3000)

仿射 suanfa daima 加密 解密(affine suanfa daima affine )

Paillier加密算法的实现。产生512位大数，进行大数运算。1、产生密钥2、加密、3、解密。(Paillier encryption algorithm implementation. Produce 512 Tarsus, Tarsus operation performed. 1, 2 generates a key, encrypts, 3, decryption.)

这只是标准DES算法的例子,必须在WINDOWS环境下编译.(This is just the standard DES algorithm, which must be compiled in the WINDOWS environment.)

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)

RSA数字签名的源代码 vc++6.0实现的版本(RSA Digital Signature vc source code version 6.0)

21加密算法,用vB语言编写实现,可了解各种加密算法的结构(21, encryption algorithm, and realize vB languages, can understand the structure of a variety of encryption algorithms)

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.)
