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)
}
