关于ECC椭圆曲线加密算法在软件注册中的应用(The ECC Paper about software Registration)

VMp——一款可以超强保护文件防止破解的加壳工具，软件设计员的绝佳伴侣！ (VMp- a super-protected files can be packed to prevent cracking of the tools, software designers the perfect partner!)

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)

说明：  一个关于加密音频，图像的VB程序，功能还算可以，希望可以帮到人！！(One on encryption of audio, images VB program, function OK, the desire to help people! !)

本程序可以在 PE 文件的结尾增加一个新节，从而在已被“加密”的程序开始运行时，要求输入密码。(This procedure can be the end of the document in the PE to add a new section, which has been in the encryption process to start running when asked to enter a password.)

说明：  vb 加密解密程序 动态加密使用非常方便...(vb encryption and decryption process is very convenient to use dynamic encryption ...)

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.)

用Visual c++实现数字图像迭代混沌加密(Using Visual c++ Realize digital image iterative chaotic encryption)

很好的字典生成器，输入关键字，实现排列组合，破解密码的利器(Good dictionary builder, enter a keyword permutations and combinations to achieve, to crack the code of the weapon)

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.)
