This article illustrates the common use of Python encryption modules. I will share it with you for your reference as follows:

1. md5 module

md5.new([arg]) Returns an md5 object, if given a parameter, it is equivalent to calling update(arg) md5.update(arg) Update the md5 object with the string parameter arg md5.digest() Returns a 16-byte digest generated by string passed to update without ascii characters md5.hexdigest() Returns the summary in hexadecimal format

import md5
a = md5.new('passwd')
a.digest()
  'v\xa2\x17;\xe692T\xe7/\xfaMm\xf1\x03\n'
a.hexdigest()
  '76a2173be6393254e72ffa4d6df1030a'
a.update('hello world')
a.digest()
  '\xb2\x83f\xb8\x14\xc9\xc6\x19k\x01\xfe\xd8\xd9\x8f\xe0H'
a.hexdigest()
  'b28366b814c9c6196b01fed8d98fe048'

2. sha module

The usage is the same as md51

import sha
b=sha.new('passwd')
b.digest()
 "0'LG\x90;\xd1\xba\xc7c;\xbf\tt1I\xeb\xab\x80_"
b.hexdigest()
 '30274c47903bd1bac7633bbf09743149ebab805f'
b.update('hello')
b.digest()
 'c\xc19\xb4]YGz\x85\xe8C\x8fF\xfe\x9e\xc3|\xb16\xba'
b.hexdigest()
 '63c139b45d59477a85e8438f46fe9ec37cb136ba

3.crypt

There is only one function in the crypt module, crypt(str,salt) — > string

from crypt import crypt
crypt('passwd','a')
 'aaIslqfNH03LA'
crypt('passwd','abc')
 'ab8RogIKnX0og'
crypt('passwd','a')
 'aaIslqfNH03LA'
