What is LTV?
 
LTV (Long Term Validation) provides a record of what state the Certificate was at the time of signing.  In order to validate a certificate, the time and date when the PDF document was signed needs to be known. For this to be undisputable, the signature has to be digitally timestamped.  Verifying a certificate requires the OCSP or CRL responder for its Certificates to be online. But how would you know if it was trustworthy 25 years ago? These considerations have led to the concept of “LTV”.
