采用bin加密的经典算法。

VPN拨号程序源码(from sourceforge.net)-VPN digit dialing procedure source code (from sourceforge.net)

2的16次幂正整数d与n，编写计算d-1 (mod n) 的程序； 2、对于三个不超过2的16次幂正整数a、e与n，编写计算ae (mod n) 的程序。 在上述程序基础上写出下列程序： （1） 对给定的10000以内数判定其是否为素数； （2） 进行ElGamal体制的加密与签名。 -two of 16 power-positive integer d and n, calculate the preparation of d-1 (mod n); 2. For not more than 2 3 16 Powers positive integers a, e and n, calculate the preparation ae (mod n) procedures. In the above procedure to write on the basis of the following procedures : (a) the right to 10,000 within a few judging whether a prime number; (2) ElGamal encryption and signature.

一个用各种加密算法给文件加密的Delphi例子。为了减小文件size把执行文件去掉了。D7下编译。-A full example that encript a file with many motheds.You should sompile it under D7.

RSA资料全集是我在学习RSA时收集的资料，它对我学习这种算法有着极大的帮助，不知对大家有帮助没有，希望对大家学习密码学有所帮助。-All of the information of RSA was collected when i was studying RSA.It gives me a great deal of help though i don t know how about you.I wish it also give you some help about the cryptology.

PGP 是一种混合密码系统。当用户使用PGP 来对纯文字加密的时候， PGP 首先会压缩这 段纯文字。数据压缩能够节省调制解调器传输时间以及磁盘类空间，还有更重要的、强化密码法的 保密程度。-PGP is a hybrid cryptosystem. When the user to use PGP to encrypt the text, PGP will first this text compression. Data compression can save time and modem transmission disk space, and more importantly, to strengthen the password confidentiality law.

AES implementation in C++. Input: key file and the file for encryption Output: the crypted file.
