No. If a signature has expired, the signature is invalid. Therefore, the Validator replies that he does not trust the key.
Regarding the procedure to be followed in order to guarantee the validity of the signature, which is currently invalid, we highlight point 5 of section 4 of the Signature Maintenance Procedure:
“ If the digital signature is technically invalid due to the expiration of the signer's certificate and not having a valid time stamp, it will be necessary:
- send it for validation on the alleged date of signature or on the date of signature contained in the document or on that date that the person responsible for the application believes that it was already hosted on the system. With the set of new validations of the signatures that are in this condition, an Index of Document Signatures will be built that lists the validated documents and signatures and relates them to the answers of the validation platform.
- that a person responsible for the document management system, or the processing platform, sign a document, which will contain the Index of Signatures of said Documents stating that they were signed, and their signatures were technically valid, at the time of entry to the system, providing as proof the validation tickets. Each entity will have to determine who is the right person to sign this document. ”
