I am trying to understand how SSL works (to know it better); I got some understanding of the concepts by referring to various online materials and docs.
The basis is: A browser receives a certificate that is signed by a valid CA. Now, for the browser to check if Certificate is actually from that CA, it will use the public key of that CA, which is installed in the browser. This is where my doubt starts.
How does the browser receive public key of a Valid CA (for example, Symantec) and then ensure that public key is actually from that Valid CA?
This seems hen and chicken problem to me; I am not an expert in this subject, I am trying to understand to shy away from my confusion.
Any help in understanding appreciated.
