Doh! Since we're padding the document out to a power of 2 (presumably
with zeroes ??), we need a way for the client to know the real length
of the data. So the Document-header should actually be:
<2 bytes: crypto key length>
<crypto key>
<2 bytes: length of real-data-length field>
<real-data-length (including metadata)>
<2 bytes: length of metadata-length field>
<metadata-length>
