Busy, yep... as always... ;)
You then need the "Secure Messaging and Rights Management Adapter"
From the Website: (http://www.symantec.com/business/products/agents_options.jsp?pcid=2244&pvid=322_1)
Secure Messaging and Rights Management Adapter
The Enterprise Vault 8.0 Secure Messaging and Rights Management Adapter replaces the following EV 7.x named adapters:
- Adapter for Microsoft Rights Management Server
- Adapter for PGP
- Adapter for Liquid Machines (LMDC)
Licensing this connector provides ability to read and index encrypted content enabling Compliance Accelerator and Discovery Accelerator to discover and review Journal content. Specifically this license enables Enterprise Vault to decrypt content secured by Microsoft Rights Management Sever, PGP encryption added by PGP Desktop (including Universal Server) and Enterprise Rights Management protections added by LiquidMachines Document Control.
So you need to make sure that your Encryption product is supported, and you need an "Additional Encryption Key" (PGP) when encrypting the messages, and make this Key available to the Adapter for decrypting the messages. Something like this ;)
