1Port of the OpenBSD `bcrypt_pbkdf` function to pure Javascript. `npm`-ified
2version of [Devi Mandiri's port](https://github.com/devi/tmp/blob/master/js/bcrypt_pbkdf.js),
3with some minor performance improvements. The code is copied verbatim (and
4un-styled) from Devi's work.

6This product includes software developed by Niels Provos.

8## API
9
10### `bcrypt_pbkdf.pbkdf(pass, passlen, salt, saltlen, key, keylen, rounds)`
11
12Derive a cryptographic key of arbitrary length from a given password and salt,
13using the OpenBSD `bcrypt_pbkdf` function. This is a combination of Blowfish and
14SHA-512.

16See [this article](http://www.tedunangst.com/flak/post/bcrypt-pbkdf) for
17further information.

19Parameters:
20
21 * `pass`, a Uint8Array of length `passlen`
22 * `passlen`, an integer Number
23 * `salt`, a Uint8Array of length `saltlen`
24 * `saltlen`, an integer Number
25 * `key`, a Uint8Array of length `keylen`, will be filled with output
26 * `keylen`, an integer Number
27 * `rounds`, an integer Number, number of rounds of the PBKDF to run
28
29### `bcrypt_pbkdf.hash(sha2pass, sha2salt, out)`
30
31Calculate a Blowfish hash, given SHA2-512 output of a password and salt. Used as
32part of the inner round function in the PBKDF.
33
34Parameters:
35
36 * `sha2pass`, a Uint8Array of length 64
37 * `sha2salt`, a Uint8Array of length 64
38 * `out`, a Uint8Array of length 32, will be filled with output
