Python hashlib模块的使用示例

import hashlib

m = hashlib.md5()

m.update(b"Hello")

m.update(b"It's me")

print(m.hexdigest())

m.update(b"It's been a long time since last time we ...")

print(m.digest())

import hashlib

s2 = hashlib.sha1()

s2.update(b"abc")

print(s2.hexdigest())

s2 = hashlib.sha256()

s2.update(b"abc")

print(s2.hexdigest())

print(len(s2.hexdigest()))

import hashlib

s2 = hashlib.sha384()

s2.update(b"abc")

print(s2.hexdigest())

print(len(s2.hexdigest()))

import hashlib

s2 = hashlib.sha512()

s2.update(b"abc")

print(s2.hexdigest())

print(len(s2.hexdigest()))

import hmac
h = hmac.new('wueiqi')
h.update('hellowo')
print h.hexdigest()

import hmac

h = hmac.new(b"xsk","y风的风x".encode(encoding="utf-8"))

print(h.digest())

print(h.hexdigest())
