Public key encryption clarification please

Hi I was wondering if someone could clarify for me the details of public to public key encryption and public to private! I have a fair understanding but I would like to know a bit more about it, for example what exactly goes into the process, such as when it's public to public i know the keys encrypted using AES or something like that but what's the deal breaker? What makes the other side acknowledge and accept the person AND what goes into whatever the deal break is to? If it is a shared secret how is that generated? I would just like to know the actual details of it.
Thanks

This is also a good explanation that I usually point people to - SSL/TLS Strong Encryption: An Introduction - Apache HTTP Server Version 2.2

Hi,

Public key is part of PKI, for example, when you open page the can be used for money transactions for example Amazon, the amazon system must have some secure tunnel connection between the user and the system in order to make safe money transaction
so in this case your browser will contact with amazon server and request for its public key, amazon will send the public key to you, you will use this public key to encrypt the data you are sending to amazon when you make the check out, amazon will receive the encrypted data that only can be decrypted via the private key of Amazon server.

you can check the PKI video from trainSignal video series about security+

thanks
