-Short Name: scrypt

-Description:
-The scrypt key derivation function was originally developed for use in
-the Tarsnap online backup system and is designed to be far more secure
-against hardware brute-force attacks than alternative functions such
-as PBKDF2 or bcrypt.
-
-We estimate that on modern (2009) hardware, if 5 seconds are spent
-computing a derived key, the cost of a hardware brute-force attack
-against scrypt is roughly 4000 times greater than the cost of a
-similar attack against bcrypt (to find the same password), and 20000
-times greater than a similar attack against PBKDF2.

-Local Modifications:
-chromium.patch
-- make it compile under Windows and accessible from C++
-- no functional changes
