What I do in Nigori for this is use DSA. Your private key, x, is the

Except, of course, by dictionary attack, hence g^x, being low
entropy, is treated as a shared secret.
Indeed, if it is low entropy (I don't think you can assume it is,
though I'll readily agree it is likely to be), then it is subject to a
dictionary attack.
