Documentation

Overview

Package encrypt implements a encrypt tool with fix salt and random salt.

Algorithm:

Give message and fix salt, return Hash(msg, Hash(salt + randSalt)) as result.

Functions

func Encode

func Encode(hash hash.Hash, msg, salt []byte) ([]byte, []byte, error)

Encode a message with fixed salt, return the encoded message and random salt

func Hash

func Hash(hashNew func() hash.Hash, key, data []byte, tohex bool) []byte

func MD5

func MD5(key, data []byte, tohex bool) []byte

func SHA1

func SHA1(key, data []byte, tohex bool) []byte

func SHA256

func SHA256(key, data []byte, tohex bool) []byte

func SHA512

func SHA512(key, data []byte, tohex bool) []byte

func SaltEncode

func SaltEncode(hash hash.Hash, msg, fixed, rand []byte) []byte

SaltEncode encode the message with a fixed salt and a random salt, typically used to verify

Example

package main

import (
	"fmt"

	"github.com/cosiner/gohper/crypto/encrypt"
)

func main() {
	password := []byte("abcdefg")
	salt := []byte("123456")
	enc, randSalt, _ := encrypt.Encode(nil, password, salt)

	if encrypt.Verify(nil, password, salt, randSalt, enc) {
		fmt.Println("Password Match")
	} else {
		fmt.Println("Password don't match")
	}
}

Output:

Password Match

func Verify

func Verify(hash hash.Hash, msg, salt, randSalt, pass []byte) bool

Verify will encode msg, salt, randSalt, then compare it with encoded password, return true if equal, else false
