Obtaining the PGP/GPG key of an author (or developer, publisher, etc.) from a public key server also presents risks, since the key server is a third-party middle-man, itself vulnerable to abuse or attacks. To avoid this risk, an author can instead choose to publish their public key on their own key server (i.e., a web server accessible through a domain name owned by them, and securely located in their private office or home) and require the use of HKPS-encrypted connections for the transmission of their public key.
