Summary of Python Encryption Method [md5 base64 sha1]

The python encryption method is summarized in this paper. To share for your reference, specific as follows:

MD5 encryption:

def md5(str):
  import hashlib
  m = hashlib.md5()
  m.update(str)
  return m.hexdigest()

base64 encryption:

import base64
s = ' I'm a string '
a = base64.b64encode(s)
print a
print base64.b64decode(a)

Output results:

ztLKx9fWt/u0rg==
 I'm a string 

sha1 encryption:

The hashlib module needs to be imported:

import hashlib
def str_encrypt(str):
  """
   use sha1 Encryption algorithm, return str Encrypted string 
  """
  sha = hashlib.sha1(str)
  encrypts = sha.hexdigest()
  return encrypts
