     Assuming that this is the DigestInfo type referenced in RFC 2437
section 9.2.1 (and it looks like it should be), Steve is correct that the
inner sequence only covers the OID and the NULL, but not the OCTET STRING,
and so its length is indeed 9 rather than 31.

I'll check into this.  It's actually from Charlie Kaufman of Iris who
should be credited...
