It's a simple python script that takes specified input file (where base64 supposed to be stored) and decode it to specified output file.
chmod a+x base64decoder.py
./base64decoder.py -i [input file] -o [output file]
or
./base64decoder.py --input [input file] --output [output file]
Let's imagine we have text.b64 file with next content (Hello World! string)
SGVsbG8gV29ybGQh
We want to decode it to result.txt text file. We execute next command
./base64decoder.py -i text.b64 -o result.txt
And we get result output file.
