I am looking for an open-source PGP key server for Linux. It will be run as a private server, i.e. only accessible to a limited group of users.
My google searches have turned up lots of public key servers. But the only source code I could find is OpenPGP Public Key Server which is quite old.
Any better suggestions? I'm happy to use a bigger software package (somethign like Zimbra) if it has PGP key server support.
