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；
x：x

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
