Decode base64 encoded file and print results to the console

So I have a file that I have already encoded with base64, now I want to decode it back but instead of creating another file, I want to decode it in the console and print the results to screen. How to do that?

encoded file string = MUhRRy1ITVRELU0zWDItNlcxSA==

FYI: this would mean first opening the file in console, then decoding the give string

Thanks

This python simple script help you instantly

import base64
encode_pass = 'ENCODED-STRING-TO-BE-DECODED'

def decode_string(string):
  decoded_bytes = base64.b64decode(string.encode())
  return decoded_bytes.decode()

decoded_password=decode_string(encode_pass)
print(f"Decoded Password: {decoded_password}")

Using base64.decode, set sys.stdout (sys.stdout.buffer.raw in python 3.x) as output.

import sys
import base64

with open('filepath') as f:
    base64.decode(f, sys.stdout)

Unless I'm overlooking something, this is as simple as reading in your encoded string and then calling the standard library's base64.b64decode function on it.

Something like:

with open(path_to_encoded_file) as encoded_file:
    print base64.b64decode(encoded_file.read().strip())
