Should there be a compile-assert here on the number of data types?

Also, do we need to have this method on *both* NigoriHandler and as a util here?
 When do you call one and not the other?

The nigori handler version will eventually call into this version (via
SyncEncryptionHandlerImpl). We have this separate though so that the
FakeSyncEncryptionHandler can use it.
