1、hashlib
import hashlib
#创建一个哈希对象
md = hashlib.md5()
#md = hashlib.sha1()
#md = hashlib.sha224()
#md = hashlib.sha25()
#md = hashlib.sha384()
#md = hashlib.sha512()
1.1 hashlib.update(arg)
1.2 hashlib.digest() #返回数字形式的哈希
1.3 hashlib.hexdigest() #返回16进制的哈希
1.4 hashlib.copy()
一般而言,用hashlib.hexdigest()就可以了
2、hmac
2.1 hmac.new(key[, msg[, digestmod]])
2.2 hmac.update(msg)
2.3 hmac.digest()
2.4 hmac.hexdigest()
2.5 hmac.copy()
要注意,上面的message都要用bytes,使用string不可以
