<?php

namespace Rogierw\RwAcme\Support;

class JsonWebKey
{
    public static function compute(string $accountKey): array
    {
        $privateKey = openssl_pkey_get_private($accountKey);

        $details = openssl_pkey_get_details($privateKey);

It seems like $privateKey can also be of type false; however, parameter $key of openssl_pkey_get_details() does only seem to accept resource, maybe add an additional type check?

        return [
            'e'   => Base64::urlSafeEncode($details['rsa']['e']),
            'kty' => 'RSA',
            'n'   => Base64::urlSafeEncode($details['rsa']['n']),
        ];
    }

    public static function thumbprint(array $jwk): string
    {
        return Base64::urlSafeEncode(hash('sha256', json_encode($jwk), true));
    }
}
