Meteor Definition

This small library handles both the generation and validation of an SLK. The library itself exposes two functions:

• generate
• is_valid

SLK.generate

The generate function takes 4 arguments:

• First Name (Full)
• Last Name (Full)
• Date of Birth (Given in YYYY-MM-DD format)
• Gender Identifier given as an integer from the following

| Gender | Identifier | |---------|-------------| | Male | 1 | | Female | 2 | | Intersex or Indeterminate | 3 | | Not stated/inadequately described | 9 |

SLK.is_valid

This function will validate a given string based off of three separate 'types'

1. A 14 character SLK in the METeOR spec, with the date of birth validated as a true date.
2. A 32 character Crockford encoded string, using a subset of characters to represent a 14 character SLK
3. A 40 character hex encoded string

The return value of the is_valid function is an object with key value pairings of passed and failed validations.

Installation

To install, simply:

npm i --save slk-js

Usage

The library itself is exposed as a global variable SLK which will be accessible anywhere in your application.

var SLK = require('slk-js').default;
import SLK from 'slk-js';

// Use the SLK library

console.log(SLK.validate('myslk'));
// false
