If you want to encrypt specific files, just use your favorite encryption
algorithm and encrypt them. If you want to encrypt the whole card,
you most probably need to develop (or use) custom firmware.
Android also has support for encrypted application packages
(encrypted filesystem in a file), but it is not public yet(?).
