Self signed certificate

Please Explain.  
Are you looking to setup a proxy for secure connections and would like to use a self-signed certificate to auth the proxy?

Your users will be warned every time they access a secure site they have not added an exception that "a man in the middle" attack is going since the certificate presented by the proxy does not match the URL to which the user is going.

Would like to use a self assigned certificate to auth the proxy.

Thanks

What do you mean?
You can not proxy secure sites.
are you looking to access your proxy as https://yourownproxy?
In this case, you have to use stunnel and have the self signed certificate on it which will then forward the requests to your squid proxy.

Often, people use certificates to auth clients to the proxy.

Information and possible implementations included.

Each person approaches a question in different ways. As NetoMeter pointed out a direct answer of yes provides a limited set of info in my opinion.
