LTV (Long-Term Validation)

Long-Term Validation (LTV) is a feature of PDF signatures (PAdES B-LT/B-LTA) that embeds within the signed document all the data necessary for future verification of the signature: certificate chain, time-stamps, OCSP responses or CRLs. Thanks to LTV, a signed document remains verifiable years after signing, even if the certificates have expired. Certyneo integrates LTV to guarantee evidentiary value for 10 years.
