A golang implementation of the bcrypt hash algorithm. It is a fork of github.com/jameskeane/bcrypt.

Installation:

go get github.com/ProtonMail/bcrypt

Example use:

package main

import (
      "fmt"
      "github.com/ProtonMail/bcrypt"
)

var password     = "WyWihatdyd?frub1"
var bad_password = "just a wild guess"

func main() {
      // generate a random salt with default rounds of complexity
      salt, _ := bcrypt.Salt()

      // generate a random salt with 10 rounds of complexity
      salt, _ = bcrypt.Salt(10)

      // hash and verify a password with random salt
      hash, _ := bcrypt.Hash(password)
      if bcrypt.Match(password, hash) {
              fmt.Println("They match")
      }

      // hash and verify a password with a static salt
      hash, _ = bcrypt.Hash(password, salt)
      if bcrypt.Match(password, hash) {
              fmt.Println("They match")
      }

      // verify a random password fails to match the hashed password
      if !bcrypt.Match(bad_password, hash) {
              fmt.Println("They don't match")
      }
}
