!!! Overview
[{$pagename}] is a [Public Key] that follows the [RSA] format.

In our [Example Certificate]. the [{$pagename}] is the hexadecimal representation of a 1,024-bit number. 

There's no further encoding here; this is the number "n" used by the [Public Key Algorithm] (typically RSA). 

Notice that it's prefixed by a 0x00 placeholder — this is used to stop some large number libraries from interpreting this as a negative two's-complement number.

If the [Protocol Client] decides to accept this certificate, it will generate yet another key, a one-time-use [Symmetric Key] and securely transmit it to the [Protocol Server] using the [Public Key Algorithm] {{{c=ke%n}}}
 
[Protocol Server] will decrypt the one-time-use [Symmetric Key] using the [Private Key] (which you can't see in the certificate for obvious reasons!) and use that key for subsequent communications.
