Encrypt Report Attachments (through Subscriptions) -- possible?

We currently email out reports as either PDF or Excel attachments using Data Driven subscriptions in SSRS 2005. I've been asked to be able to encrypt the attachments and am wondering if anyone has done this or can point me in the right direction.

There's been a couple of mentions about "encrypted email" -- but I don't know where to find further information. Is this possible using SSRS subscriptions?

Thanks in advance,

Currenlty, the way to do this is to write a custom delivery extension. The one provided with reporting servcies does not support encrypting the report.
