You could just remove all the CA's from your browser and it would be nearly the same as using SSH. The only thing the CA is doing is answering this question for you:<p><pre><code> The authenticity of host 'x.x.x.x (x.x.x.x)' can't be established.
RSA key fingerprint is 2f:db:11:aa:b0:13:48:64:50:cc:94:73:7b:aa:57:78.
Are you sure you want to continue connecting (yes/no)?
</code></pre>
Removing CA's without an alternative in place such as Web of Trust means that users have no assurance that the other end of the connection is who it claims to be.
