Signing PDF's

1. offizieller Beitrag

    I suspect there isn't any direct support, but is there anything that might help sign PDFs with a digital signature? Given how easy it is to break the "no editing/selection" option on PDFs, I think our app will need to sign PDFs to ensure integrity. If there is any sort of support or code for doing this in wPDF then that would be very handy. Please point me at anything that might help - we are at the research stage of this project.

    Thanks, Matthew

    Hi,

    "Signing" is something which is done with a complete PDF file, it creates a checksum over the PDF file and adds in an additional object which contains the encrypted sum + the public key. wPDF cannot do this, sorry.
