sfcc_jwt

An implementation of JSON Web Tokens for Salesforce Commerce Cloud SFRA.

Install

Install the cartridge on server & add it to cartridge path.

Usage

jwt.sign(payload, options)

Returns the JsonWebToken as string.

payload is an object literal representing valid JSON.

options:

• privateKeyOrSecret is a string containing either the secret for HMAC algorithms or the private key for RSA.
• algorithm HS256, RS256 or similar
• kid

Sign with HMAC SHA256

var jwt = require('plugin_jwt');
var options = {};
options.privateKeyOrSecret = 'my_secret';
options.algorithm = 'HS256';
var token = jwt.sign({ foo: 'bar' }, options);

Sign with RSA SHA256

var privateKey = 'my_private_key';
var options = {};
options.privateKeyOrSecret = privateKey;
options.algorithm = 'RS256';
var token = jwt.sign({ foo: 'bar' }, options);

jwt.verify(token, options)

Returns a boolean signifying if the signature is valid or not.

token is the JsonWebToken string

options:

• publicKeyOrSecret is a string containing either the secret for HMAC algorithms or the public key for RSA or a function which will return an appropriate JSON Web Key Set for a kid. This function should return a modulus & exponential which then will be used to generate a DER format of public key.
• ignoreExpiration is a boolean to skip JWT expiration time verification.
• audience is a string containing JWT audience.
• issuer is a string containing JWT issuer.

Verify HMAC SHA256

var jwt = require('plugin_jwt');
var token = 'my_token';
var options = {};
options.publicKeyOrSecret = 'my_secret';
var isValid = jwt.verify(token, options);

Verify RSA SHA256

var publicKey = 'my_public_key';
var token = 'my_token';
var options = {};
options.publicKeyOrSecret = publicKey;
var isValid = jwt.verify(token, options);

jwt.decode(token, options)

Returns the decoded payload without verifying if the signature is valid.

token is the JsonWebToken string

var decoded = jwt.decode(token);

Algorithms supported

Array of supported algorithms. The following algorithms are currently supported.

Example

Check JWTTest.js controller for SFRA example.
