dln

dln-go

Cuvva's library to generate, parse, and validate GB DVLA issued driving licenses.

Usage

import (
    "github.com/cuvva/dln-go"
)

Generate

From a set of user details, generate a DLN. It cannot generate the last 3 digits though as they are not based on any user details that can be provided. Additionally, you may chose to not generate the middle name character too by passing false in as a 2nd argument.

userDetails := dln.UserDetails{
    PersonalName: "Charles",
    FamilyName: "Bbaee",
    Sex: "M",
    BirthDate: "1975-07-01",
}

d, err := dln.Generate(userDetails, true)
if err != nil { /* do something */ }

// d = BBAEE707015C9

Validate

Validate a DLN against a set of user details. It will return true/false depending if the details match or not. Once more, you can chose to ignore the middle name.

d := "BBAEE707015C99WY"
userDetails := dln.UserDetails{
    PersonalName: "Charles",
    FamilyName: "Bbaee",
    Sex: "M",
    BirthDate: "1975-07-01",
}

isValid, err := dln.Validate(d, userDetails, true)
if err != nil { /* do something */ }

// isValid = true

Parse

From a DLN, attempt to parse out the user details. This is not a lossless conversion, and you will loose details. Once again, you may chose to ignore any middlenames.

d := "BBAEE707015C99WY"

userDetails, err := dln.Parse(d, true)
if err != nil { /* do something */ }

/*
userDetails := dln.UserDetails{
    PersonalName: "C",
    FamilyName: "Bbaee",
    Sex: "M",
    BirthDate: "1975-07-01",
}
