I've had professors do many different things, Blackboard is actual okay for checking your grades as a student though it does suck to put grades in. Another option is set up a website with a login id (student id or something) and have students submit a pin (4-12 chars) and let them use that to login and see their grades (probably should be ssl). As for your question I don't see how you could send them encrypted, you could make up random ids for each student and only give that student their id then send grades out corresponding to their random ids but that may still violate privacy issues.
