Thanks for the info guys saved this post for future reference, just an idea thought it might be cool having military grade encryption ^_^

sorry again, meant PGP keys not PHP keys. However, since you will need to do this in PHP, you should take a look at the GPG module for php here: https://www.php.net/manual/en/intro.gnupg.php

note that my reply has to do with using PHP keys for messaging; don't see how/why you'd want to login using a pgp key.

I don't see why you need to implement it in the core files. You would need to:

1) Store a public and private key for each user, you can either augment the ossnusers table or make your own additional table.
2) make a component that does the encryption/decryption routines on messages right before they are sent and right after being received. you _could alternatively do this by editing the OssnMessages component, but it's not suggested to do that.

Hmm ... sounds completely confusing to me ...

So ... when I log in to your community, I would no longer use
username: ~Z~
password: heybabe

but f26807c5f615e5ad5d91a9479a3d9f4f (my PGP private key) or what?

Hmm, i think it would be possible, though the option would be optional for users who want more privacy etc, Facebook offers PGP login i think but might be just sharing of your PGP ID.

I am not sure if it would be easier for the regular users to first learn about PGP and then generate it.
