Band files JSON key content

edited November 20 in Windows

I've recently started using 1Password and I have a question about the content of band files in opvault directory in order to backup or clone in the future that content.

I see that the uuid is the same as the log writes when I create a new password, for example, but I don't know what are the "o", "k", "d" and "hmac" keys.

Could you clarify what are them saving? I've taken a look at this but it didn't help me too much

Thanks in advance. Regards.

    Welcome to the forum, @jjfreire! I'm not surprised you didn't get far in your search for answers in our Security White Paper. As informative a document as the white paper is, it concerns our account system, not the format of our older, standalone vaults (OPVault). Fortunately, we do fully document the OPVault format so you should be able to find answers to your questions there. Feel free to let us know if you have remaining questions, however. Cheers!

  • Thank you so much, @Lars! I'll take a look and I'll comment again if doubts arise. Cheers!
