simple-argon2 provides a convenience wrapper around Go's existing argon2 (formaly argon2id) package that makes it easier to securely derive strong keys ("hash user passwords").

Based on article How to Hash and Verify Passwords With Argon2 in Go and strongly inspired of package (source code, comments & readme).

The API closely mirrors Go's bcrypt library in an effort to make it easy to migrate—and because it's an easy to grok API.


go get
package main

import (

  argon2 ""

func main() {
  hashed, err := argon2.GenerateFromPasswordString("42password42", argon2.Default)
  if err != nil {
  // $argon2id$v=19$m=65536,t=3,p=2$/lASHr1GVXVkV/628wFUVGqINrLbWo7v86TjaooJmUY$igyAvrODju4SsBSefcYOzMaLl9xGjSkjsY1tnaKaTxk

  err = argon2.CompareHashAndPasswordString(hashed, "42password42")
  if err != nil {
    // Invalid password

  // Valid password
