NAME

	passcheck - passphrase strength evaluator

SYNOPSIS

	passcheck [OPTION]... < PASSPHRASE_LIST

DESCRIPTION

	Evaluates the strength of passphrases based.

	All passphrases are given a non-negative integer rating.

	The output is formatted so that it is suitable for

	piping into 'sort -rn' to sort passphrases by strength.

	300 is a good threshold for strong passphrases,

	200 is a good threshold for acceptable passphrases.

OPTIONS

	-r

	--raw

		Treat escape sequences as part of the passphrases.

		If not used, ANSI escape sequences are ignored.

	-w

	--waste-ram

		Loads the blacklist into RAM and creates a hash set

		of it. It is unreasonable to do this unless you have

		the process running indefinitely and (somewhat)

		continuously feed passphrases. Note that this

		requires a lot of RAM.

RATIONALE

	Passphrase-strength meters used on the Web use horrid

	heuristics and does not even blacklist the most common

	passphrases. We need better passphrase-strength meters

	to keep users safe.
