Java算法md5 的相关内容

在Java中利用Apache Commons Codec API实现常见的加密解密算法，如：md5,sha256

实际上，在这个jar包里已经封装好了相关的加密解密算法，我们只需要调用相关方法即可实现目的，当然为了方便在项目中频繁使用，我们可以将相关的方法统一封装在一个方法类中一导入jar包在Javaweb项目中，将commons-codec-1.10.jar放入 WEB-INF/lib 中...

Java 常用加密算法(一)---单向加密算法(MD5/SHA)

MD5加密 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。在MD5算法中，首先需要对信息进行填充，使其位长对512求余的结果等于448。因此，信息的位长（Bits...

java单向加密算法小结(2)--MD5哈希算法

　　上一篇文章整理了Base64算法的相关知识,严格来说,Base64只能算是一种编码方式而非加密算法,这一篇要说的MD5,其实也不算是加密算法,而是一种哈希算法,即将目标文本转化为固定长度,不可逆的字符串(消息摘要). 简单了解　　MD5(Message Digest Algorithm 5),...

JAVA上加密算法的实现用例MD5/SHA1，DSA，DESede/DES，Diffie-Hellman的使用(转)

源文作者王辉第1章基础知识 1.1. 单钥密码体制单钥密码体制是一种传统的加密算法，是指信息的发送方和接收方共同使用同一把密钥进行加解密。通常,使用的加密算法比较简便高效,密钥简短，加解密速度快，破译极其困难。但是加密的安全性依靠密钥保管的安全性,在公开的计算机网络上安全地传送和保管密钥是一个...
