Description: 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 < q，x为私钥 ；
y：y = g^x mod p ，( p, q, g, y )为公钥；
H( x )：One-Way Hash函数。DSS中选用SHA( Secure Hash Algorithm )。
p, q, g可由一组用户共享，但在实际应用中，使用公共模数可能会带来一定的威胁。签名及验证协议如下：
1. P产生随机数k，k < q；
2. P计算 r = ( g^k mod p ) mod q
s = ( k^(-1) (H(m) + xr)) mod q
签名结果是( m, r, s )。
3. 验证时计算 w = s^(-1)mod q
u1 = ( H( m ) * w ) mod q
u2 = ( r * w ) mod q
v = (( g^u1 * y^u2 ) mod p ) mod q
若v = r，则认为签名有效。
DSA是基于整数有限域离散对数难题的，其安全性与RSA相比差不多。DSA的一个重要特点是两个素数公开，这样，当使用别人的p和q时，即使不知道私钥，你也能确认它们是否是随机产生的，还是作了手脚。RSA算法却作不到。

Description: 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-512 (这些有时候也被称做 SHA-2)。
-SHA (Secure Hash Algorithm, Secure Hash Algorithm translated) is a U.S. National Security Agency (NSA) design, the U.S. National Institute of Standards and Technology (NIST) released a series of password hash function. Formally known as the SHA family members of the first release in 1993. But now people take it the informal name of a SHA-0 in order to avoid confusion of its successor. Two years later, SHA-1, the first successor to SHA issued. There are four variants have been released to enhance the output of some minor changes to the scope and design: SHA-224, SHA-256, SHA-384 and SHA-512 (these are sometimes also known as SHA-2).

Description: SHA 252
SHA-2 is a set of cryptographic hash functions designed by the NSA (U.S. National Security Agency).[3] SHA stands for Secure Hash Algorithm. Cryptographic hash functions are mathematical operations run on digital data by comparing the computed hash (the execution of the algorithm) to a known and expected hash value, a person can determine the data s integrity. For example, computing the hash of a downloaded file and comparing the result to a previously published hash result can show whether the download has been modified or tampered with.[4] A key aspect of cryptographic hash functions is their one-way nature: given only a computed hash value, it is generally impossible to derive the original data.
SHA-2 includes significant changes its predecessor, SHA-1. The SHA-2 family consists of six hash functions with digests (hash values) that are 224, 256, 384 or 512 bits: SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, SHA-512/256.-SHA 252
