Signing using iText, Adobe Reader reports “Signature was created using Not available.”
I am successfully signing documents using iText. However, any time that I check the "Advanced Signature Properties" in Adobe Reader I see that the "Signature was created using Not available." My question is, how can I use iText update this piece of information to then display properly in Adobe Reader or any other PDF reader?
