If people have bad passwords, that makes brute force recovery of the private key on a Keybase server plausible, right? At least a lot more so than the whole key from scratch. I'd assume that a machine generated key has more entropy than any password that a human can memorize. If sharing a password-protected private key is perfectly safe, why bother having them? Why don't PGP users just password protect everything? Ab…
I think people are confusing things a bit here. Sure, you can protect your pgp key with a password, but I don't think that adds a whole lot of security to your uploaded private keys. When you upload a pgp key to keybase, it encrypts the key again, using your keybase device key. So its double encrypted, basically. The keybase model revolves around devices. Device keys are private keys that are tied to a particular dev…
At the end of the day, your keybase device key is, itself, simply encrypted with your keybase password. The point I've been trying to make clear is:
> Your private keys are as secure as any private, encrypted piece of data that you might send out over the wire, so long as your devices are secure, that is.
