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.
