Does SecureBlackbox support the incremental update facility for PDF? Is it possible to sign the signed document without breaking the first signature?

You can take any of our existing samples and use already signed document as an input. It will work. The samples are located in \EldoS\SecureBlackbox.<edition>\Samples\<language>\PDFBlackbox folder.

Hello Igor,

SecureBlackbox always uses incremental updates when adding signatures to existing documents, so all the existing signatures will be kept intact.
