PAdES (PDF Advanced Electronic Signature)

PAdES (PDF Advanced Electronic Signature, ETSI EN 319 142 standard) is the European standard for digital signatures embedded in PDF files. It comes in four profiles of increasing maturity: B-B (basic signature), B-T (with time-stamping), B-LT (long-term validation) and B-LTA (archiving with recertified time-stamping). Certyneo produces PAdES B-LT PDFs, guaranteeing offline verifiability in Adobe Acrobat Reader and lasting evidentiary value. See also XAdES / PAdES / CAdES →
