I believe the argument is that a private key encrypted with a password is not cryptographically different from a plaintext private key. The password is more of a "keeping honest people honest" kind of thing, than true security. If it was truly secure, then you'd be using a new private key to encrypt your real private key, and then you're back to where you started. Cryptography is hard, which is why I was such a big f…
I didn't downvote. Here are my thoughts. > I believe the argument is that a private key encrypted with a password is not cryptographically different from a plaintext private key. You have it backwards. On principle an encrypted anything (key in this case) is of zero value to anyone. It does’t matter if you tweet encrypted messages every 30 seconds to millions of followers or not: they're encrypted. When you use a pas…
If sharing a password-protected private key is perfectly safe, why bother having them? Why don't PGP users just password protect everything?
Above all else though, is there an authoritative source that can answer these questions? As a run-of-the-mill programmer, I don't really understand how crypto works well enough to trust my own common sense here. It's been drilled into my head that there are certain rules to follow set out by people who do know what they're doing. And when people say "it's all good, it's password protected", and I'm not sure what their credentials are, I get a little nervous. I did notice that Werner Koch uses Keybase, but if they could simply point to an "okay" from him or Zimmerman explaining the situation, it would be settled. To me anyway, it's not simply an abundance of caution ("paranoia"), it's that something seems fundamentally wrong with the approach and I just don't know the actual cost.
