    • Method Detail

      • setPrivateKey

        public final void setPrivateKey​(PrivateKey privateKey)
      • setCertificateChain

        public final void setCertificateChain​(Certificate[] certificateChain)
      • sign

        public byte[] sign​(InputStream content)
                    throws IOException
        SignatureInterface implementation. This method will be called from inside of the pdfbox and create the PKCS #7 signature. The given InputStream contains the bytes that are given by the byte range. This method is for internal use only. Use your favorite cryptographic library to implement PKCS #7 signature creation.
        Specified by:
        sign in interface org.apache.pdfbox.pdmodel.interactive.digitalsignature.SignatureInterface
        content - the content of the file
        IOException - cannot write the PDF file
      • setExternalSigning

        public void setExternalSigning​(boolean externalSigning)
        Set if external signing scenario should be used. If false, SignatureInterface would be used for signing.

        Default: false

        externalSigning - true if external signing should be performed
      • isExternalSigning

        public boolean isExternalSigning()
      • getMDPPermission

        public int getMDPPermission​(org.apache.pdfbox.pdmodel.PDDocument doc)
        Get the access permissions granted for this document in the DocMDP transform parameters dictionary. Details are described in the table "Entries in the DocMDP transform parameters dictionary" in the PDF specification.
        doc - document.
        the permission value. 0 means no DocMDP transform parameters dictionary exists. Other return values are 1, 2 or 3. 2 is also returned if the DocMDP transform parameters dictionary is found but did not contain a /P entry, or if the value is outside the valid range.
      • setMDPPermission

        public void setMDPPermission​(org.apache.pdfbox.pdmodel.PDDocument doc,
                                     org.apache.pdfbox.pdmodel.interactive.digitalsignature.PDSignature signature,
