RSA算法的C++实现。公钥加密算法中使用最广的是RSA。RSA算法研制的最初理念与目标是努力使互联网安全可靠，旨在解决DES算法秘密密钥的利用公开信道传输分发的难题。-RSA algorithm is the C++ implementation. Public key encryption algorithm is the most widely used is RSA. RSA algorithm is developed by the original idea and objective is to make the Internet safe and reliable, aimed at resolving the DES algorithm is a secret key transmitted using the open channel distribution problems.

另一个使用java编写的加密通用算法包，含des,rsa,sha,md5,md4,md2,idea,blowfish等很多加密算法和密钥存储、签名等源码- Another uses the java compilation the encryption general algorithm package, contains des, rsa, sha, md5, md4, md2, idea, blowfish and so on the very many encryption algorithm and the key saves, source code and so on the signature

从一个随机文件读取256字节数据形成数据区DArea，再应用洗牌法所给的方法生成0~255的一个全排列DTab。试分别写出"求DArea中全部数据经 （1）以DTab为S-盒； （2）以DTab为P置换 -from a random file read 256 byte data area DArea form data, re-shuffling in law application to the formation of 0 ~ 255 DTab a full array. Try to write were "seeking DArea by which all data (1) DTab S-boxes; (2) DTab replacement for the P

ElGamal算法不仅用于数据加密也能用于数字签名，其安全性依赖于有限域上离散对数问题的计算。该方法的关键。首先，选择一个素数P，两个随机数，G和G，X，X＜P，计算Y = G ^ X（MOD P），其公钥Y，G和P的私钥X G和P的一组用户共享。ElGamal数字签名。信息签署M，先选择一个
