Which document formats does VIDsigner support and what kind of signatures does it use?

VIDsigner always works for PDF documents, both in input and output formats.

The signatures created with VIDsigner are PADES B-LT, which means the following:

PADES is the signature format used by PDFs and has several levels.

LT (Long Term) is a signature format that includes a series of evidence (timestamp, revocation data...) in the document, which guarantees that the signature will be valid beyond the validity period of the issued certificate.
