【下载】RSA1024及RSA2048加密算法漏洞CVE-2017-7526 问题出在GnuPG加密库

专家通过对RSA密钥发起侧信道攻击，可破解GnuPG加密库的RSA-1024加密算法。安全研究人员近期发现了一个严重漏洞。该编号为CVE-2017-7526的漏洞存在于隐私保护软件GnuPG（也称为GPG）的加密库中，利用此漏洞，研究人员可破解RSA-1024加密算法，提取RSA密钥以解密数据。研...

Java 常用加密算法(二)---对称加密(DES/3DES(TripleDES)/AES)

基于“对称密钥”的加密算法主要有DES、3DES（TripleDES）、AES、RC2、RC4、RC5和Blowfish等。代码中用到的Base64与BouncyCastleProvider的jar包可在本文末尾下载源码，从源码获取jar包。 DES DES算法全称为Data Encryption...

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...
