)

Hash

var password = "password"
var hash, salt, version = hasher.Hash(password)
// save hash, salt and version to database

Verify

var password = "password"
// get hash, salt and version from database
var ok = hasher.Verify(password, hash, salt, version)
if ok {
    // The password is correct
}

CLI tool
