SP Signing Certificate - Store details

[ntbutler-nbcs]

Hi all.

I'm trying to build an app that has more of a front-end to manage SAML settings. How can I get the laravel-saml2 package to pull the certificate from somewhere other than the .env file?

In the /config/saml2.php file, the comment on the SP Certificates seems to indicate that the files could be stored in a particular folder, but I haven't been able to figure out how to get that to work. The actual config seems to simply pull the values from the .env file.

        /*
        |--------------------------------------------------------------------------
        | SP Certificates.
        |--------------------------------------------------------------------------
        |
        | Usually x509cert and privateKey of the SP are provided by files placed at
        | the certs folder. But we can also provide them with the following parameters.
        |
        */

        'x509cert' => env('SAML2_SP_CERT_x509',''),
        'privateKey' => env('SAML2_SP_CERT_PRIVATEKEY',''),

Part of my plan is to incorporate the idea from PR #81 (commit 026d5b7) to make cert generation/renewal simple. Ideally if the files are just generated into a target folder that the SAML2 plugin picks up from, that'd be awesome.

At this stage, I don't seem to get anywhere at all if I don't have the SAML2_SP_CERT_x509 and SAML2_SP_CERT_PRIVATEKEY properties in the .env file. Until I enter and populate those, I just get this error when I try to auth
