一个完全使用java编写的加密通用算法包，含des,des3,rsa等很多加密算法源码- Completely uses the java compilation the encryption general algorithm package, contains des, des3, rsa and so on very many encryptions calculates the law origin code

算术运算实现字母的替换。凯撒加密就是一种单字母替换法：通过用户给出密钥将字母加上密码变成密文-Arithmetic operations to achieve the replacement of letters. Caesar encryption is the replacement of a single-letter law: the user is given the letter key will be encrypted into a ciphertext

上传一个很好的加密算法。-Upload a very good encryption algrithm

MD5以512位分组来处理输入的信息，且每一分组又被划分为16个32位子分组，经过了一系列的处理后，算法的输出由四个32位分组组成，将这四个32位分组级联后将生成一个128位散列值。 -MD5 with 512-bit packet to process the input information, and each group was again divided into 16 32-seat group, after a series of processing, the algorithm" s output consists of four 32-bit group composed of these four 32-bit Cascade Group will generate a 128-bit hash value.

利用DELPHI的INDY来快速制作MD5加密的演示-DELPHI the INDY use to quickly create MD5 encryption demonstration

RC4 encryption algorithm implementation

vb写的DES源码，复制到Visual Basic 6.0 中即可使用。-vb source code written by DES, copy to the Visual Basic 6.0, can be used.

通过对OpenSSL对称密码算法函数的调用，实现常用的对称加密。这个工具主要的功能已经实现，而且还可以对大文件进行加密，可能效率上还需进一步完善，因为对大文件加密时，太差劲的电脑会感觉有点卡！另外，它还可以对电影加密，不妨一试。-Symmetric cryptographic algorithm through OpenSSL function calls to achieve common symmetric encryption. The main function of this tool has been achieved, but also can encrypt large files, you may need to further improve efficiency, because the large file encryption, too bad the computer will be felt Dianka! In addition, it can encrypt the film, worth a try.

代码详细的将DES算法的加密过程描述详细，通过MFC进行界面化操作，整体界面良好，具有很强的可读性和很好的独立性，突出了C++的封装型和继承性的有点，值得参考。。。。。。。。。。。。。。。。
