What is the best PGP program, commercial products included?
Easy and streamlined email integration for common clients.
Easy to encrypt single files with simple GUI.
Some kind of trusted centralized key managing service for common PGP needs (tracking public keys, revoking keys, etc.)
Must be strongly GUI based. Command line features wont be used.
I am aware of the command line clients, but I need something with much better integration in a GUI enviornment. Consider price no object.
