Hi,

I have started using FusionAuth recently and I'm facing an issue I have not been able to solve.
I'm using the PHP library to perform a SSO login through the API, to a docker container which hosts FusionAuth.

I am first getting the code that I have to include in the SAML token.
Then I am getting the certificate (from the keys that I have registered in FusionAuth) to generate a signed token.
And finally I submit my login request to the api.

The token that I'm generating contains a signature which is validated via the xmlseclibs library.

Every time I get the same error, "The signature is invalid".
The key for the signing of the token is set in "Identity Providers" (Verification key and Options/Request signing key) and in "Applications" (Default verification key).

Any help would be appreciated.
Thank you in advance.
