uuid-apikey

"API Keys for people"

A generator, validator, and converter that transforms UUIDs into human-readable Base32-Crockford encoded API Keys.

• API Keys are 31 characters in length consisting of 4 groups of 7 characters separated by dashes (e.g. XXXXXXX-XXXXXXX-XXXXXXX-XXXXXXX)
• They avoids the problem that Base64 encoded values can create
  • Fully upper-case, but treat lower-case for their equivalents (e.g. a = A)
  • No tricky characters, but treat them equivalently (i.e. 0 = O / 1 = L = I )
  • No characters that inadvertently lead to common profanities (i.e. letter U is omitted)

One common use for this library is in REST APIs, by storing a UUIDs in a host DB but displaying the human-readable API Key to a user. Another use for this library is creating and validating product keys for distributed software.

NOTE: This package makes use of ES6 and ES7 functionality. If you are using a version of node prior to version 8 then you will probably need to use a polyfill (e.g. babel) for compatibility.

Installation

You can install uuid-apikey with NPM.

npm install uuid-apikey

Usage

const uuidAPIKey = require('uuid-apikey');

console.log(uuidAPIKey.create());

Output:

{ uuid: '0b9ca335-92a8-46d8-b477-eb2ed83ac927',
  apiKey: '1EEA6DC-JAM4DP2-PHVYPBN-V0XCJ9X' }

Command Line

uuid-apikey installs with a command line tool. The tool is available using the command apiKeyTool which can be install globally using:

  npm install uuid-apikey -g

Options

$ apiKeyTool.js

  Usage: apiKeyTool [options]


  Options:

    -V, --version          output the version number
    -g, --generate         Create a new API Key/UUID pair. Ignores other parameters if passed.
    -u, --uuid <uuid>      UUID for operation. If no other parameter is passed this is converted to an API Key.
    -a, --apikey <apikey>  API Key for operation. If no other parameter is passed this is converted to an UUID.
    -c, --check            Check the API Key and/or UUID provided are valid. If both API Key and UUID are passed then they are checked against each other.
    -h, --help             output usage information

Examples

Generation

$ apiKeyTool.js -g

  UUID(9b3ac4c9-0228-4e42-a244-927059b1a5ea)
APIKey(KCXC9JD-08M4WGH-M9294W1-B6RTBTH)

Conversion

$ apiKeyTool.js -a KCXC9JD-08M4WGH-M9294W1-B6RTBTH -u 9b3ac4c9-0228-4e42-a244-927059b1a5ea

UUID(9b3ac4c9-0228-4e42-a244-927059b1a5ea) => APIKey(KCXC9JD-08M4WGH-M9294W1-B6RTBTH)
APIKey(KCXC9JD-08M4WGH-M9294W1-B6RTBTH)    => UUID(9b3ac4c9-0228-4e42-a244-927059b1a5ea)

Testing

$ apiKeyTool.js -a KCXC9JD-08M4WGH-M9294W1-B6RTBTH -u 9b3ac4c9-0228-4e42-a244-927059b1a5ea -c

UUID(9b3ac4c9-0228-4e42-a244-927059b1a5ea) : valid
APIKey(KCXC9JD-08M4WGH-M9294W1-B6RTBTH)    : valid
UUID & APIKey are identical                : true

API Reference

.isUUID(uuid)

Tests if the UUID string passed is a valid UUID.

uuidAPIKey.isUUID('0b9ca335-92a8-46d8-b477-eb2ed83ac927');
uuidAPIKey.isUUID('NodeJS');

Output:

true
false

.isAPIKey(apiKey)

Tests if the API Key string passed is a valid API Key.

uuidAPIKey.isAPIKey('1EEA6DC-JAM4DP2-PHVYPBN-V0XCJ9X');
uuidAPIKey.isAPIKey('NodeJS');

Output:

true
false

.toAPIKey(uuid, [options])

Converts a valid UUID into an API Key. Throws a TypeError if the UUID is invalid.

uuidAPIKey.toAPIKey('0b9ca335-92a8-46d8-b477-eb2ed83ac927');
uuidAPIKey.toAPIKey('0b9ca335-92a8-46d8-b477-eb2ed83ac927', { 'noDashes': true });

Output:

'1EEA6DC-JAM4DP2-PHVYPBN-V0XCJ9X'
'1EEA6DCJAM4DP2PHVYPBNV0XCJ9X'

Options

.toUUID(apiKey)

Converts a valid API Key into an UUID. Throws a TypeError if the API Key is invalid.

uuidAPIKey.toUUID('1EEA6DC-JAM4DP2-PHVYPBN-V0XCJ9X');

Output:

'0b9ca335-92a8-46d8-b477-eb2ed83ac927'

.check(apiKey, uuid)

Test that an API Key and a UUID are identical. Throws a TypeError if either the API Key or the UUID is invalid.

uuidAPIKey.check('1EEA6DC-JAM4DP2-PHVYPBN-V0XCJ9X', '0b9ca335-92a8-46d8-b477-eb2ed83ac927');

Output:

true

.create([options])

Returns a new UUID and API Key pair

uuidAPIKey.create();

Output:

{ uuid: '0b9ca335-92a8-46d8-b477-eb2ed83ac927',
  apiKey: '1EEA6DC-JAM4DP2-PHVYPBN-V0XCJ9X' }
