> Passwords are PSKs and are the overwhelming default authentication mechanism for Internet scale systems. Not for HTTPS, which is what we're talking about. For WPA2-PSK, okay, you have a small n, it might work. For user authentication against a local database, you're not encrypting, you're using validating against a password hash and then elevating the user's privilege for the duration of their session. That's far removed from what we mean when we say PSK (pre-shared keys), where encryption is implied.
