AES相关的一些列子,需要库的支持才能应用

DSA算法的Pascal实现和例子。实现了签名和确认-DSA algorithm Pascal realization and example. Realized has signed and confirmed

Converst a bit array into a single byte and vice versa

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

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.

这是密码学软件源码,一个小程序的源码,caser密码-This is the source cryptography software, a source of small procedures, caser password

一个伪随机数生成程序，简单实用，有需要的请下载-A pseudo-random number generator, if necessary, please download the

DIAMOND加密算法的原代码-separate encryption algorithm source code

音频的水印加入算法，采用matlab实现-joined audio watermarking algorithm, using Matlab to achieve

des加密算法源码-Sourcecode of des encrypting algorithm

本代码实现了维吉尼亚密码，维吉尼亚密码是基于简单的凯撒密码改进而来的多表替换密码，代码简单，供交流学习使用。
