Just my 5ø:

Raised awareness does seldom lead to change (just as knowledge and
attitudes). Before developing a strategy on promoting the use of 
GPG, the barriers which prevent people from using it should be 
explored and fed back into the implementation strategy.

Maybe some principles from social marketing (insight, exchange..) 
would fit as a good starting point for a campaign.
