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.
