Key (JWK) and Key Set (JWKSet)

To perform cryptographic operations (signature/verification and encryption/decryption), you will need keys.

The JWK object is part of the web-token/jwt-core component:

composer require web-token/jwt-core

JWK

A JWK object represents a key. It contains all parameters needed by the algorithm and also information parameters.

This framework is able to create private and public keys easily. It can also generate those keys from external resources.

JWKSet

The keys can be grouped in key sets. A JWKSet object represents a key set. It can contain as many keys as you need.

We strongly recommend you to avoid mixing public, private or shared keys in the same key set.
