Installation

git clone https://github.com/AmpersandHQ/okta-jwt-verifier-php-example
cd okta-jwt-verifier-php-example
composer install

Usage

Run like so, but replace the URL with your valid okta URL

$ php request.php https://dev-12345.okta.com/oauth2/default/v1/keys
Sent request to https://dev-12345.okta.com/oauth2/default/v1/keys
Duration 0.85608506202698

Caveats

This will show a little additional runtime than the raw request due to the call also running self::parseKeySet but most of the duration is in the actual requesting of data

public function getKeys($jku)
{
    $keys = json_decode($this->request->setUrl($jku)->get()->getBody()->getContents());
    return self::parseKeySet($keys);
}

This is corroborated by using curl and seeing most of the time spent in appconnect and connect

$ curl -XGET -H 'Accept: application/json'  -w '\n\ntime_total: %{time_total}s\ntime_appconnect: %{time_appconnect}s\ntime_connect: %{time_connect}s\ntime_namelookup: %{time_namelookup}s\ntime_pretransfer: %{time_pretransfer}s\ntime_redirect: %{time_redirect}s\ntime_starttransfer: %{time_starttransfer}s\n'  https://dev-12345.okta.com/oauth2/default/v1/keys
