Password-Based Cryptography via pbkdf2

Documentation

Overview

Example (Verify)

hasher := new(PBKDF2Hasher)
pwd := "testpwd"
hash := hasher.EncodeDefault(pwd)
ok, _ := hasher.Verify(pwd, hash)
fmt.Printf("%v", ok)
ok, _ = hasher.Verify("wrongPwd", hash)
fmt.Printf("%v", ok)

Output:

truefalse

Types

type PBKDF2Hasher

type PBKDF2Hasher struct {
}

func (PBKDF2Hasher) Decode

func (p PBKDF2Hasher) Decode(str string) (dict map[string]string, err error)

Decode just splits string by $

func (PBKDF2Hasher) Encode

func (p PBKDF2Hasher) Encode(pwd, salt string, iterations int) string

Encode as defined in RFC 2898

func (PBKDF2Hasher) EncodeDefault

func (p PBKDF2Hasher) EncodeDefault(pwd string) string

EncodeDefault as defined in RFC 2898 and default args in const

func (PBKDF2Hasher) GenSalt

func (p PBKDF2Hasher) GenSalt(size int) string

GenSalt Generate a cryptographically secure nonce salt in ASCII.

func (*PBKDF2Hasher) Verify

func (p *PBKDF2Hasher) Verify(pwd string, cipher string) (bool, error)

Verify password with ciphertext
