rjzak / randomKey.py

Created February 17, 2016 17:22

For when you need some random keys as a string, with optional starting value and optional length

	import random
	def randomKey(start=None, bytes=16):
	if start is None:
	part = "%02x" % random.randint(0,255)
	return randomKey(part, bytes)
	elif len(start.split(" ")) == bytes:
	return start
	else:
	part = "%s %02x" % (start, random.randint(0,255))
	return randomKey(part, bytes)

rjzak / magic.py

Last active January 2, 2016 17:39

Compare magic numbers (or the first 32 bytes of a file) with the output from the file command (which also uses magic numbers). The intention is to discover magic numbers for different file types. For example, to be able to distinguish between different MS Office document types, since libmagic just says "CDF V2 Document, Little Endian, Os" or "Zi…
