3des 加密,可以进行3des,des等其他基本加密算法-3des

This program encodes and decodes a character using the Vigenere Square method

简单的密码的例子，使用VB的源码, 非常简单明了，希望大家喜欢。-Simple Example of VB Source Code for Encrypt, Rudimentary encryption/decryption demo program

access数据库加密有几法，但用“设置安全机智向导”加密最为牢靠，又如何访问这样的数据库呢-access database encryption with a few laws, but "to provide a safety witty guide" the most secure encryption, how to access such a database?

c# DES文件加密 c# DES文件加密-c# DES file encryption file encryption c# DES

vb中实现的md5-vb achieve the md5

MD5文件签名算法的另一个实现-MD5 algorithm to achieve another

公钥加密程序，采用非对称密钥，这里以类的形式调用-Public key encryption procedures, the use of non-symmetric key, where to type the form of call

DES密码体制的安全性应该不依赖于算法的保密，其安全性仅以加密密钥的保密为基础-DES password security system should not depend on secrecy algorithm, the only security encryption key based on the confidentiality
