PGP keyserver
From StackWiki
Stack operates a public PGP Keyserver. This keyserver offers a directory where the public PGP keys (with additional signatures) of thousands of users can be looked up. The database can be searched by keyid, username or email address. This server runs the SKS software and automatically synchronises its data with other PGP keyservers.
The server can be accessed via the website or directly via HKP (Horowitz Key Protocol). Most PGP clients, such as GnuPG have built-in HKP support. To search for a PGP key using GnuPG, one could use the following command
gpg --keyserver keyserver.stack.nl --search unix@stack.nl
