It was my understanding that a Blob Filter would process the data as it
is written into the Blob, compress it or encode it, and then uncompress
or unencode when the blob is read out.

This is supposed to be a way to make sensitive data more secure, so that
without the filter, a copy of the database would be of little use.

Have I got it wrong? Which is quite possible :)
