| I use GPG quite often but there are many annoying issues: - Lacking GPG support on iOS devices, the available apps are not integrated with Mail.app (iOS). - GPG support on OS X devices is usable with Mail.app and GPG Tools ((https://gpgtools.org/) but encrypted mails are not searchable. I use folders etc. but it is still often a pain do browse manually through mail after mail until you find the one you've been looking for … - Webmail, for example Gmail or Outlook.com, and GPG don't fit together well – if at all. - The public keychain is not made for use on more than one device, i.e., it's not sync-ready. - Key verification is bothersome, i.e., you have to attend key signing parties etc. - There are political issues, e.g., should you upload your keys to key server? If so, with or without signatures? If you upload signatures, you create not only a web of trust but you also expose at least parts of your address book. - Key servers store long invalid keys and there is no way to remove such keys. The PGP.com key server removes keys if you don't confirm them by mail from time to time. On the other hand, the PGP.com key server only accepts one key per mail address. - Etc. |
