Installation:
    goinstall github.com/jameskeane/bcrypt

Example use:
  package main

  import (
        "fmt"
        "github.com/jameskeane/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")
        }
  }
