python MD5加密的示例

# 方式一：
pwd = '123456'
# 生成MD5对象
md5 = hashlib.md5()
# 对数据加密
md5.update(pwd.encode('utf-8'))
# 获取密文
pwd = md5.hexdigest()
print(pwd)

#方式二：

pwd = '123456'
pwd = hashlib.md5(bytes(pwd,encoding = 'utf-8'))
print(pwd.hexdigest())



# 输出结果
e10adc3949ba59abbe56e057f20f883e
e10adc3949ba59abbe56e057f20f883e

# MD5加盐值(SALT)


pwd = '123456'
# 生成MD5对象
md5 = hashlib.md5(b'~!@@#!#$DFDT@#$@#')
# 一下两种方式与上面效果等同
# md5 = hashlib.md5('~!@@#!#$DFDT@#$@#'.encode('utf-8'))
# md5 = hashlib.md5(bytes('~!@@#!#$DFDT@#$@#',encoding='utf-8'))
#

# 对数据加密
md5.update(pwd.encode('utf-8'))
# 获取密文
pwd = md5.hexdigest()
print(pwd)63e87e46fc935f18abb6b38bb0376fee
