scala3-bcrypt

scala3-bcrypt is a scala friendly wrapper of Password4j

Setup

libraryDependencies += "com.github.roundrop" %% "scala3-bcrypt" % "0.1.0"

Usage

Hash password

scala> import com.github.roundrop.bcrypt._
                                                                                                                             
scala> "password".bcrypt()
val res0: scala.util.Try[String] = Success($2a$10$KH/WkRKeqCYJXbR2IcheRO9BORWMRw5SaY0YTRiIjb2u2uhsY/AH.)

Validate password

scala> "password".isBcrypted("$2a$10$KH/WkRKeqCYJXbR2IcheRO9BORWMRw5SaY0YTRiIjb2u2uhsY/AH.")
val res1: scala.util.Try[Boolean] = Success(true)

Advanced usage

By default, the salt generated internally, and developer does not need to generate and store salt. But if you decide that you need to use an existing salt, you can use bcrypt in the following way:

scala> val salt = "$2a$13$8K1p/a0dL1LXMIgoEDFrwO"
val salt: String = $2a$13$8K1p/a0dL1LXMIgoEDFrwO
                                                                                                                                                   
scala> val hash = "my password".bcrypt(salt)
val hash: scala.util.Try[String] = Success($2a$13$U9hCpYnHwj2LwOy49rwQFeymCsLvvlvrIm.dNf9moxn0DxJPrQsIK)

scala> "my password".isBcrypted(hash.get)
val res2: scala.util.Try[Boolean] = Success(true)
