Digital Signature Algorithm (DSA)是Schnorr和ElGamal签名算法的变种,被美国NIST作为DSS(DigitalSignature Standard)。算法中应用了下述参数:
p:L bits长的素数。L是64的倍数,范围是512到1024;
q:p - 1的160bits的素因子;
g:g = h^((p-1)/q) mod p,h满足h < p - 1, h^((p-1)/q) mod p > 1;

SHA (Secure Hash Algorithm,译作安全散列算法) 是美国国家安全局 (NSA) 设计,美国国家标准与技术研究院 (NIST) 发布的一系列密码散列函数。正式名称为 SHA 的家族第一个成员发布于 1993年。然而现在的人们给它取了一个非正式的名称 SHA-0 以避免与它的后继者混淆。两年之后, SHA-1,第一个 SHA 的后继者发布了。 另外还有四种变体,曾经发布以提升输出的范围和变更一些细微设计: SHA-224, SHA-256, SHA-384 和 SHA-51

MD5是一个安全的散列算法,输入两个不同的明文不会得到相同的输出值,根据输出值,不能得到原始的明文,即其过程不可逆;所以要解密MD5没有现成的算法,只能用穷举法,把可能出现的明文,用MD5算法散列之后,把得到的散列值和原始的数据形成一个一对一的映射表,通过比在表中比破解密码的MD5算法散列值,通过匹配从映射表中找出破解密码所对应的原始明文。
对信息系统或者网站系统来说,MD5算法主要用在用户注册口令的加密,对于普通强度的口令加密,可以通过以下三种方式进行破解:
(1)在线查询密码。一些在
