sha1 - Java - Efficient (native?) version of PBKDF2WithHmacSHA1 -


i using pbkdf2withhmacsha1 hash passwords. (might sound weird, thats not part of discussion).

the issue: implementation of java damn slow. 2000 iterations take ~2 seconds on machine. native implementation of openssl needs same input 0.05 seconds. while not security want (because c fast) way slow (i can not go beyond 2000 rounds without pissing users since hashing done client side).

can give me suggestion or poke me @ library?
