I gotta say there are parts of this that are quite ugly with Acrobat. Yes I get a GUI that helps me create self-signed certs and incorporate a "real" digitized signature (scanned or photographed); but it puts the signature file in a f'n obscure location and 3 out of 4 migrations to new systems and versions of Acrobat I either can't figure out where that file is, or once I find it, the new version won't eat the old signature. So now I have probably 5 self-signed digital signature files floating around all with different passwords. And with self-signing there's no verification of the signer. All we really know is whether the document has been modified since it was signed, and maybe if the public key has since been revoked (although I'm not sure how that mechanism works). I still find it better than faxes, and I won't send PDFs with merely an image of my signature because such PDFs can be altered while providing neither party a way to prove or disprove that alteration. http://www.adobe.com/devnet-docs/acrobatetk/tools/DigSig/Acrobat_DigitalSignatures_in_PDF.pdf -- Chris Murphy -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
