Simple python script to byte encode a string

bc.py

import array, sys

ARGV = sys.argv
if len(ARGV) <= 1 or not ARGV[1]:
	print 'usage: ' + ARGV[0] + ' <string to encode>'
	sys.exit(1)


inp = str(ARGV[1])
bc = ''
for item in [elem.encode("hex") for elem in inp]:
	bc = bc + '\\x' + item

print bc

# Decode, just for a prove
print bc.replace('\\x', '').decode("hex")

how to decode back at the other end?

That's easy. Taken the string bc from above it would be:

print bc.replace('\\x', '').decode("hex")
