passcheck

passcheck is a package and CLI tool to check passwords against the Pwned Password API.

Usage

Package

First, install the package:

go get -u github.com/dbarbuzzi/passcheck

The simplest use-case is to create a new API client using NewPwnedPasswords and then pass a password and the client to Check to get the pwnage results for that password:

// main.go
package main

import (
	"fmt"

	"github.com/dbarbuzzi/passcheck"
)

func main() {
	client, err := passcheck.NewPwnedPasswords("https://api.pwnedpasswords.com")
	if err != nil {
		panic(err)
	}

	count, err := passcheck.Check("password", client)
	if err != nil {
		panic(err)
	}

	fmt.Printf("Password has been pwned %d times.\n", count)
}

$ go run main.go
Password has been pwned 3730471 times.

A few other functions are available to check a hash instead of a password (so you don’t need to give the password to this package) or to check multiple passwords/hashes.
