romuloceccon / b32backup.py

Last active September 24, 2016 20:16

A tool to convert small binary files to text suitable to be printed on paper. It uses Base32 encoding so that the result is easily parseable with OCR software and every line includes a CRC16 for error verification. Efficiency is about 3000 bytes per page using a 10-pt font!

	#! /usr/bin/env python

	# Examples:
	#
	## encoding
	#
	# $ head -c 135 /dev/urandom \| b32backup.py
