	10 Description:

	11 The scrypt key derivation function was originally developed for use in

	12 the Tarsnap online backup system and is designed to be far more secure

	13 against hardware brute-force attacks than alternative functions such

	14 as PBKDF2 or bcrypt.

	15

	16 We estimate that on modern (2009) hardware, if 5 seconds are spent

	17 computing a derived key, the cost of a hardware brute-force attack

	18 against scrypt is roughly 4000 times greater than the cost of a

	19 similar attack against bcrypt (to find the same password), and 20000

	20 times greater than a similar attack against PBKDF2.
