Data Encryption and Decryption Using By Triple DES Performance Efficiency Analysis of CryptosystemCryptography plays very important role in security of data. Cryptography means to transfer sensitive information across insecure networks like internet so that it cannot be read by anyone except the person ...
DES 数据加密标准(英语:Data Encryption Standard,缩写为 DES)是一种对称密钥加密块密码算法,1976年被美国联邦政府的国家标准局确定为联邦资料处理标准(FIPS),随后在国际上广泛流传开来。它基于使用56位密钥的对称算法。这个算法因为包含一些机密设计元素,相对短的密钥长度以及怀疑内含美国国家安全局(NSA)的后门而在开始...

This is an online tool for Triple DES encryption and decryption. This tool provides both CBC and ECB modes of encryption and decryption. Also plain text can be encoded both with padding and without padding
注:以下示例需引用命名空间 using System.Security.Cryptography 一. DES 加密、解密 我相信一下注释相当清楚了,加上我博客里关于DES的文章确实不少,所以DES不做任何解释,怎么调用就更不用解释了吧,呵呵: //默认密钥向量 private byte[] Keys = { 0xEF, 0xAB, 0x56, 0x78, 0x90, 0x34, 0xCD, 0x12 }...
一)对称加密(Symmetric Cryptography) 对称加密是最快速、最简单的一种加密方式,加密(encryption)与解密(decryption)用的是同样的**(secret key)。对称加密有很多种算法,由于它效率很高,所以被广泛使用在很多加密协议的核心当中。 对称加密通常使用的是相对较小的**,一般小于256 bit。因为**越大,加密越强,但加密与...
