public abstract class SignedSignatureField extends SignatureField

A base class for signature fields that have been signed

The existence of a signed signature field does not imply that the signature is valid. The signature is not validated at all.

  • Method Details

    • getName

      public String getName()

      The name of the person or authority that signed the document (Getter)

      This is the name of the signing certificate.

      Note: The name of the signing certificate can only be extracted for signatures conforming to the PAdES or PDF standard and not for proprietary/non-standard signature formats. For non-standard signature formats, the name as stored in the PDF is returned.

      Throws:
      IllegalStateException - If the object has already been closed

    • getDate

      public OffsetDateTime getDate()

      The date and time of signing (Getter)

      This represents the date and time of signing as specified in the signature. For signatures that contain a time-stamp, the trusted time-stamp time is returned.

      Note: The value can only be extracted for signatures conforming to the PAdES or PDF standard and not for proprietary/non-standard signature formats. For non-standard signature formats, the date as stored in the PDF is returned.

      Throws:
      IllegalStateException - If the object has already been closed

    • getRevision

      public Revision getRevision() throws CorruptException

      The document revision (Getter)

      The revision (version) of the document that the signature signs.
      Throws:
      IllegalStateException - If the object has already been closed
      CorruptException - If the signature specifies an invalid document revision
