Three months ago, we explained how to download our self-signed Acrobat certificate and use it to verify the signatures on PDF issues of MDJ and MWJ.
As it turns out, self-signed certificates are good for five years, and we started using Acrobat’s own technology to sign PDF issues five years ago last week (2002.07.17). We can’t sign any new issues with it, although it’s still valid for verifying issues we signed with it.
Today we’ve issued a new self-signed certificate, available here or from our certificates and security settings page here.
