The same problem exists in 5.4.1 version. in I text if you want to have multiple signature you must create stamper like this
PdfStamper stp = PdfStamper.CreateSignature(reader, output, '\0',null, true); but stp.SetEncryption(chain, new int[] { PdfWriter.ALLOW_FILL_IN }, PdfWriter.ENCRYPTION_AES_128); this code give an exception "append.mode.does.not support.changing.the encryption.status" so what I want is encrypt a pdf for one person and and also sign it for two different person -- View this message in context: http://itext-general.2136553.n4.nabble.com/how-to-encrypt-a-pdf-after-multiple-signature-tp4658313p4658323.html Sent from the iText - General mailing list archive at Nabble.com. ------------------------------------------------------------------------------ AlienVault Unified Security Management (USM) platform delivers complete security visibility with the essential security capabilities.
