Thanks for the reply.

I don't have my project posted. The main parts involve replacing the SQLite
databases with SQLCipher databases to encrypt all the .sqlite files and
using NSS to encrypt the non-sqlite files at the stream level. I am still
working out the details, such as providing a key for SQLCipher and a
key/initialization vector for NSS.

For key3.db, I understood that it contains information about the master
password and another key used to unlock signons.sqlite. Considering I can
encrypt signons.sqlite (with a separate key not contained in key3.db),
should I bother messing with key3.db?

Cheers,

- Denis
