des和rsa加密算法程序

软件有限次加密，对软件的使用次数进行限制-finite encryption software, software usage restrictions

使用标准C++开发的SHA-1算法的实现-Using standard C++ Developed SHA-1 algorithm

产生共享软件加密序列号的程序- Has the shareware encryption sequence number procedure

JAVA密码保护页面,可以保护你不让想看的人，设置简单-JAVA password-protected pages, and can protect you from those who want to set up a simple

这是我的密码学算法 Algorithm. 我已经习惯了的哈希算法该算法。这种算法不是反向或解密，而且不可能。

完整的EVRC压缩解压缩算法源码,附带一个简单的例子程序。-EVRC complete source compression decompression algorithms, with a simple example program.

除了上面提到的压缩方法，你也可以调用VB的工具MakeCab.exe（在VB5setupkitkitfil32或VB98WizardsPDWizard目录下）生成.cab文件。先构造一个Directive 文件(*.ddf)，然后使用Shell命令调用MakeCAB /f excel.ddf就可以生成*.cab文件。关于Directive 文件的格式，可以参考MSDN Library中的《MakeCAB: A Compression and Disk Layout Tool》一文。 -addition to the above-mentioned methods of compression, you can call VB Tools MakeCab.exe (VB5 setupkit kitfil32 or VB98 Wizards PDWizard directory) production. Cab document. First constructed a Directive document (*. DDF), then use the Shell order call MakeCAB/f excel.ddf can generate*. cab documents. Directive on the document format, they can refer to the MSDN Library "MakeCAB : A Disk Compression and Layout Tool," a text.

I think this the first time every one can look at a PE crypter source in top level language such VC++. So as I promised ... if some one sent me one nice compress source I would publish my source. I dedicate this source to all people who involve in this field. I hope it helps someone. Have good days ashkbiz Check: yodap.cjb.net

使用的是BCB5开发的一个简单的3DES的DEMO，对文件采用的是密文挪用来处理短块。-Using BCB5 developed a simple 3DES of DEMO, the document is used ciphertext diverted to deal with the short block.

椭圆曲线公钥密码算法,可用于加密和数字签名等应用，该版本算法是有限域GF（2^n）上的算法-Elliptic curve public key cryptography algorithms can be used for encryption and digital signature applications, the version of the algorithm is a finite field GF (2 ^ n) the algorithm
