API in asp.net for digital certification -- 2

I need an API, developed in asp.net core with good practices and security implementation, which allows me to sign and validate the electronic signature in records of a table to be provided. I need all that to follow the specification of the manual attached.

Needs:

-Validate Certificate

-Provide time-stamped hashed bank records

-Validate signature

-To allow revalidation of the signature

-Allow export of signed registration

-Allow the time-stamp to be added later in case of unavailability

-Listing of pending signatures to be corrected

-Load to import already signed records with validation

-View subscription information

-Log of all actions taken, failures, errors, etc.

-Allow PDF files to be signed following the same standards

For the time-stamp I will provide an external service provider. More details when we star the project.
