Update Method

Updates a signature.


public func update() throws -> Void


PDF signature may be updated from time to time by embedding newer/missing revocation information. The update approach is typically used to extend validity of an LTV signature.

Updating is typically accompanied with a document timestamping operation. Set TimestampServer to have the class obtain and embed a document timestamp for you.

Before calling this method, provide the signed document via InputFile (or InputStream) property. The updated document will be saved to OutputFile (or OutputStream).
