PdfSignature EnableLTV vs CreateLongTermValidity

[Alejandro]

Good day!

I'm posting this message because I cannot find an answer to my quest, which is: what is the difference (if any) between setting:

PdfSignature.EnableLTV = true;

and calling

PdfSignature.CreateLongTermValidity(certs) ?

I tried to find information in the online documentation and in the forums, but I'm not able to determine when to use one or another (or both?)

Thank you for clarifying me this

Regards

Alex
