Hi all,

Years we are working with libraries to sign ncr pdf documents, adding the timestamp on the documents.
But now, we have a doubt.

A customer asks us if we signed with format PAdES-LTV (Long term Validation).

I understand that the libraries signing with PAdES format, but we dont know if the LTV works or as applied.

Somebody could indicate the operation of LTV-PAdES?

Thank you
