PHC Crypto

Inspired by Upash, also implementing PHC string format

Usage

Currently there are two options of using this package:

1. Import all
2. Import specific hash function

Bear in mind, these usage function might be changed in the near future.

Currently supported formats

• Bcrypt
• Argon2i & Argon2id
• PBKDF2
• Scrypt

For details regarding configs, please refer to their own directory.

Option 1 - Import all

package main

import (
	"fmt"
	"github.com/aldy505/phc-crypto"
)

func main() {
	// Create a crypto instance
	// Change the scope name to your prefered hashing algorithm
	// Available options are: Bcrypt, Scrypt, Argon2, PBKDF2
	crypto, err := phccrypto.Use(phccrypto.Scrypt, phccrypto.Config{})

	hash, err := crypto.Hash("password123")
	if err != nil {
		fmt.Println(err)
	}
	fmt.Println(hash) // returns string ($scrypt$v=0$p=1,ln=32768,r=8$402ffb0b23cd3d3a$62daeae2ac...)

	verify, err := crypto.Verify(hash, "password123")
	if err != nil {
		fmt.Println(err)
	}
	fmt.Println(verify) // returns boolean (true/false)
}

Option 2 - Import specific hash function

package main

import "github.com/aldy505/phc-crypto/scrypt"

func main() {
	// Change the scope name to your prefered hashing algorithm
	hash, err := scrypt.Hash("password123", scrypt.Config{})
	if err != nil {
		fmt.Println(err)
	}
	fmt.Println(hash) // returns string ($scrypt$v=0$p=1,ln=32768,r=8$402ffb0b23cd3d3a$62daeae2ac...)

	verify, err := scrypt.Verify(hash, "password123")
	if err != nil {
		fmt.Println(err)
	}
	fmt.Println(verify) // returns boolean (true/false)
}

Contribute

Yes please! I'm still new to Go and I create this module (or package if you will) to help me fulfill a need on my project. Feel free to refactor, add new feature, fix unknown bugs, and have fun!
