**
** tool to dump the underlying encoding of a database. This tool duplicates
**  some private functions in softoken. It uses libsec and libutil, but no
**  other portions of NSS. It currently only works on sqlite databases. For
**  an even more primitive dump, use sqlite3 on the individual files.
**
**   TODO: dump the meta data for the databases.
**         optionally dump more PKCS5 information (KDF/salt/iterations)
**         take a password and decode encrypted attributes/verify signed
**             attributes.
