python MD5操作

def my_md5(str):
    import hashlib
    new_str = str.encode() #把字符串转成bytes类型
    # new_str = b'%s'%str  #把字符串转成bytes类型
    m = hashlib.md5()  #实例化md5对象
    m.update(new_str)  #加密
    return m.hexdigest()  #获取结果返回

m = hashlib.md5()

print(m.__doc__)

Methods:

update() -- updates the current digest with an additional string
digest() -- return the current digest value
hexdigest() -- return the current digest as a string of hexadecimal digits
copy() -- return a copy of the current hash object

Attributes:

name -- the hash algorithm being used by this object
digest_size -- number of bytes in this hashes output
