Public key encryption and Certificate DigSign

guys

How to sign a document with my private key (in order to ensure that the document is intact) and then encrypt the document using the public key of the receiver (in order that only the recipient can open the document).

PDFLeo 1 does not support PDF signing. However you can encrypt PDF using public key security. Public security requires the public key of recipient only.

http://mdn.morovia.com/manuals/pdfleo-1 ... php#N10580

Code: Select all
pdfleo --encrypt=discard;AES-128 \
      --pubkey-recipient=thomas_tang.cer;joe_smith.cer;modify=none;print=low;extract=yes


The resulted PDF is now encrypted with AES-128, and only the person who possess private key that corresponds to thomas_tang.cer can open the PDF file.
