Possible to detect if a message is PGP encrypted/signed (ciphertext)
Somewhat related: there's even an XKCD on this ;-) xkcd.com/1181
Why does WPA-PSK not use Diffie-Hellman key exchange?
I don't get why this is the accepted answer. While it does provide an overview of the key establishment situation, it does not answer the question. I agree with @lxgr: in presence of an attacker that knows the PSK, it seems weird not to use DH. The PSK is not a secret at this point.
