PDFs can support file attachments and annotations, and PDFpen now fully embraces that, which is handy because it lets a PDF file act as a kind of portmanteau or a sticky-note festooned marked-up copy. If it’s yellow with an X inside, you can click it and see that a self-signed certificate was used, and obtain more information about the certificate. If the triangle is green and has a checkmark, the app has verified it clicking the corner brings up additional technical details. PDFpen shows that a PDF is signed by displaying a triangular notch in the upper-right corner. PDFpen even includes a process to create a self-signed certificate, which is useful for showing a document wasn’t tampered with but doesn’t help assure identity. You can use certificates from Adobe’sĪdobe Approved Trust List (AATL), which can cost from about $150 to $300 a year as an individual, as well as so-called self-signed certificates that you can create yourself. PDFpen now supports validating signatures signed by Acrobat and other software, as well as adding such verification itself. (In this case, I trusted a self-signed certificate.) (There are ways outside of the PDF for assuring that the right person has access to those keys and it’s the person you think it is.)Ī valid digital signature in a PDF displays as a green checkmark in the upper right. (I don’t work inside a corporation or in industries that require document validation.) A securely signed document allows a recipient to verify both that the PDF is unchanged since it was signed and that it was sent by a person who had access to a given set of private keys associated with an identity. The PDF format and Adobe Acrobat supported digital certificates starting years ago, although I’ve never seen a signed document in the wild. (Unless otherwise noted, all new features are available in both editions.) Smile has focused on several areas that mix tools and tasks useful to individuals, groups, and people in companies or exchanging secure documents.

For those who already use or know PDFpen, let me jump to the chase about new features.
