Authly::JWKS::PublicKey

Inherits Struct < Value < Object

A public key read from a PEM PUBLIC KEY (SubjectPublicKeyInfo) or RSA PUBLIC KEY (PKCS#1). Private keys are refused outright.

The key must be of the kind the algorithm signs with: RS* an RSA key, ES256/384/512 an EC key on P-256/P-384/P-521. Publishing a key under an algorithm it cannot verify would mislead clients. kid is the RFC 7638 thumbprint, so it follows the key.
