EGPG

eGPG utilizes a centralized GnuPG installation and key-ring for encrypting and decrypting files, not a new concept, but it eliminates the need for key-ring importation after the client installation in an enterprise environment, while increasing key security... eGPG eliminates the security risk of the public exposure of the private key. Using the centralized key-ring the client and user only has access to the private key for decryption only. The private key sits on your locked and secure server, not on the user's machine.
