If the HTTPS webserver uses self signed certificate, the web browser warns the user as follow.
I am curious how can browser tell if the certificate is self signed or not(in detail). is there any technically detailed document which describes this process?
thank you in advance.
You can find the complete detail in RFC5246.
Put very simple: Every certificate should be signed by a third party. Each third party's certificates are included within your browser. The browser can check if the certificate is signed by a third party it trusts, if it's signed by the same server of which you are demanding to see the identity, then it's considered self signed.
