I actually just went to the first website google came up with base64
decode which gave me:


I then did a guess and cut the string at the + to see what I got then,
at which point I got


which I figured was the salt. I am not sure how well that guess will
work but you could try a visual check with the following python:

import base64


for A in FILE:
    print a
    print x

Just realize it will output data which will make a terminal lockup etc
so redirect it to a file
