Ok. That's still fairly large. Whether it's too large is difficult to say,
but I would suggest they avoid anything over 3192 as a test.

Unless that credential is only used for metadata verification or something
like that, that's not really useful anyway. There might be a bug in some
of the code around handling keyless credentials, but since you don't ever
need that, it's minor.

You need a private key. Or you don't install one at all. You don't install
a certificate as a credential with no key along with it.

No, that's not how this works. You are confusing encryption and signing,
and in either event, I don't know what certificate you're talking about or
what that has to do with this. You don't install their certificate
anywhere, it's in the metadata you have to supply. If they're encrypting,
they have to have your public key, and you'd have to have your private key

There is no response from SP to IdP. If you mean requests, those aren't
signed by default anyway.
