Python使用hashlib模块做字符串加密，pythonhashlib,hashlib是个专门提

hashlib是个专门提供hash算法的库，现在里面包括md5, sha1, sha224, sha256, sha384,sha512，使用非常简单、方便。 md5经常用来做用户密码的存储。而sha1则经常用作数字签名。

[Python]代码

#-*- encoding:gb2312 -*-import hashliba = "a test string"print 'md5 = %s' % (hashlib.md5(a).hexdigest(),)print 'sha1 = %s' % (hashlib.sha1(a).hexdigest(),)print 'sha224 = %s' % (hashlib.sha224(a).hexdigest(),)print 'sha256 = %s' % (hashlib.sha256(a).hexdigest(),)print 'sha384 = %s' % (hashlib.sha384(a).hexdigest(),)print 'sha512 = %s' % (hashlib.sha512(a).hexdigest(),)

将输出：

md5 = b1a4cf30d3f4095f0a7d2a6676bcae77sha1 = 2da75da5c85478df42df0f917700241ed282f599sha224 = fb29c0daf4a995d2caad4cc5150a6977f871ac34c1c9c97d740d90d0sha256 = b830543dc5d1466110538736d35c37cc61d32076a69de65c42913dfbb1961f46sha384 = 1b7c9d326961a90d6fe5e168b7339852a6238af953e5cad5501d140167bdfe8ebd82d7df5f7915ebad3e2f89d977357fsha512 = fd308aadbf52384412c4ba3e2dfe3551e0faa2e7455898dae04fda4f238569e3889c56cbd4d120cf69f81a5f06456f327c19100eaed2e590888342f1ce3e0261
