Simple python script to trnasform std input to base64 encoding

#! /usr/bin/python

import base64
import sys

encoded = base64.b64encode(sys.stdin.read())

print encoded

If you have binary data, you can encode it with
ascii character to store it more safely.
base64 module is an efficient choice to do so.
It uses characters from this set
('=' is used for padding at the end.)

ABCDEFGHIJKLMNOPQRSTUVWXYZ
abcdefghijklmnopqrstuvwxyz
0123456789+/

Here's how to use it.

>>> import base64
>>> base64.encodestring('hello world')
'aGVsbG8gd29ybGQ=\n'
>>> base64.decodestring(_)
'hello world'
>>>

If the text is long, the base64 module will split
the encoded data into multiple lines.
If you don't wan't it to be split. You can use
binascii.b2a_base64 instead of base64.encodestring and
binascii.a2b_base64 instead of base64.decodestring
