PYTHON-BASE64 encoding and decoding

Base64 Coding principle:

For example:

Example one:

#-*- coding: UTF-8 -*-

__author__ = ‘007’
__date__ = ‘2015/12/23’


Import base64


Code = "aGV5LOatpOWkhOWtmOWcqGpvb21sYea8j+a0nu+8jOivt+WPiuaXtuiBlOezuyB4eHh4eHhAMTI2LmNvbSDkv67lpI3mraTmvI/mtJ4="

Print type(code)
Cc = base64.decodestring(code)
Print cc

u = u‘hey, there is a joomla vulnerability here, please contact xxxxxx@126.com to fix this vulnerability ‘
Print type(u)
d = u.encode(‘utf8‘)
Print type(d)

Dd = base64.encodestring(d)
Print dd 

Operation Result:

<type ‘str‘>
Hey, there is a joomla vulnerability here, please contact xxxxxx@126.com to fix this vulnerability.
<type ‘unicode‘>
<type ‘str‘>

Example two:

#-*- coding: UTF-8 -*-

__author__ = ‘007’
__date__ = ‘2016/2/15’
