Package pbkdf2

==============

Package pbkdf2 implements PBKDF2 key derivation function.

(Slightly modified version of https://bitbucket.org/taruti/pbkdf2.go,

with password helper functions removed)

Functions

---------

### func WithHMAC

	func WithHMAC(hash func() hash.Hash, password []byte, salt []byte, iterations int, outlen int) []byte

WithHMAC derives key of length outlen from the provided password, salt,

and the number of iterations using PKCS#5 PBKDF2 with the provided

hash function in HMAC.

Caller is responsible to make sure that outlen < (2^32-1) * hash.Size().

Example

-------

	package main

	import (

		"fmt"

		"crypto/rand"

		"crypto/sha256"

		"github.com/dchest/pbkdf2"

	)

	func main() {

		password := "hello"

		// Get random salt

		salt := make([]byte, 32)

		if _, err := rand.Reader.Read(salt); err != nil {

			panic("random reader failed")

		}

		// Derive key

		key := pbkdf2.WithHMAC(sha256.New, password, salt, 9999, 64)

		fmt.Printf("%x", key)

	}
