      • Signature

        public Signature​(byte[] certificateRawData,
                 String password)
        Initializes a new instance of the Signature class.
        Parameters:
        certificateRawData - The certificate as a binary data (byte array).
        password - The certificate's password.

        public Signature​(byte[] certificateRawData,
                 String password,
                 Instant signatureDate,
                 byte[] signatureImage,
                 String signingContact,
                 String signingLocation,
                 String signingReason)
        Initializes a new instance of the Signature class.
        Parameters:
        certificateRawData - the certificate as a binary data (byte array).
        password - the certificate's password.
        signatureDate - the date and time of the digital signature. If left null, the signature will be timestamped at the millisecond that the PdfDocument is saved to Disk or Stream.
        signatureImage - a visual image for the sign, often a PNG of a human signature or company stamp (optional).

        This appends a visual signature in addition to cryptographic signing.

        signingLocation - the physical location the PDF was signed (optional).
        signingReason - the reason the PDF was signed (optional).
