In that case I wonder why you try it. You are right, WINCER_SIGNED is ADOBE_PPKMS, thus PdfSigGenericPKCS.PPKMS is used which in turn initializes the subfilter to PdfName.ADBE_PKCS7_SHA1 which as mentioned before implies SHA1 use for document hashing. As also mentioned before, you had better use adbe.pkcs7.detached or ETSI.CAdES.detached; I would suggest starting with SignDetached() from "How to sign with an external signature dictionary using BouncyCastle CMS"; you also might need more reserved space (csize), 4000 Bytes might be a bit small. > At the moment it signs the document, but the signature as invalid when I > check it.
