The Ubuntu keyserver below does not verify your keys email address but is a new maintained keyserver which may implement verification in the future. I would suggest using verifying keyservers: GPG Mail provides public key email encryption and signing. Verifying keyservers are new servers which verify the email addresses of uploaded keys, and are designed to be ”resistant to the abuse and privacy issues that plague old SKS Keyservers”. GPG Mail is a commercial extension for Apple Mail which comes as part of GPG Suite, a software collection that provides easy access to a collection of tools designed to secure your communications and encrypt files.

Several new PGP Keyservers have been written since which implement the HKP Protocol Hansen SKS Keyserver Network Under Attack. Encrypt, decrypt, sign and verify mails using OpenPGP with a few simple clicks. For details, see this post by the maintainer of the GnuPG FAQ Robert J. 34 alternatives to GPG Suite GPG for Mail is an open source plugin for Apple Mail.

They got hacked in June 2019 and got taken down permanently. To add a little more detail to what nit2savvy has written:īasically, PGP Keyservers were running on SKS-Keyserver code written decades ago and unmaintained. GPG suite itself is free, but the included GPG mail plugin for Mail.app only includes 30-day trial and then it’s paid software.
