常用模块之hashlib模块
用于加密相关的操作,3.x里代替了md5模块和sha模块,主要提供 SHA1, SHA224, SHA256, SHA384, SHA512 ,MD5 算法
import md5 hash = md5.new() hash.update('admin') print hash.hexdigest()
import shahash = sha.new() hash.update('admin') print hash.hexdigest()
import hashlib# ######## md5 ########hash = hashlib.md5()
hash.update('admin')
print hash.hexdigest()# ######## sha1 ########hash = hashlib.sha1()
hash.update('admin')
print hash.hexdigest()# ######## sha256 ########hash = hashlib.sha256()
hash.update('admin')
print hash.hexdigest()# ######## sha384 ########hash = hashlib.sha384()
hash.update('admin')
print hash.hexdigest()# ######## sha512 ########hash = hashlib.sha512()
hash.update('admin')
print hash.hexdigest()
以上加密算法虽然依然非常厉害,但时候存在缺陷,即:通过撞库可以反解。所以,有必要对加密算法中添加自定义key再来做加密。
import hashlib# ######## md5 ########hash = hashlib.md5('898oaFs09f')
hash.update('admin')
print hash.hexdigest()
还不够吊?python 还有一个 hmac 模块,它内部对我们创建 key 和 内容 再进行处理然后再加密
import hmac
h = hmac.new('wueiqi')
h.update('hellowo')
print h.hexdigest()
不能再牛逼了!!!
