If the user closes the website and opens again, a new session key would be created. 6) Similarly, when browser sends the data to the Google server it encrypts it with the session key which server decrypts on the other side. 5) When Google sends the data like requested HTML document and other HTTP data to the browser it first encrypts the data with this session key and browser decrypts the data with the other copy of the session key. Now, see, server and browser both have got the same copies of session key of the browser. 2) After validating the certificate, browser creates a new key let’s call it Session Key and make 2 copies of it. 1) As I mentioned, Google sends its public key when you enter .

What I don't understand is, couldn't a hacker just intercept the public key it sends back to the "customer's browser", and be able to decrypt anything the customer can? You should also consider supporting HTTP/1.1 over unencrypted HTTP and then redirect to HTTPS version (which will then use HTTP/1.1 or HTTP/2 as appropriate). The web is moving towards HTTPS more and more and web browsers are starting to put more and more warnings when a website is served over unencrypted HTTP. It basically wraps HTTP messages up in an encrypted format using SSL/TLS. I have a TWebBrowser with the .Silent property set to True, but it's still popping up the message Revocation information for the security certificate for this site is not available.
What are public keys and private keys?
Server certificate is a must and client certificate is optional (only when the server requests it). It also describes the symmetric/asymmetric encryption which is used for SSL certificates and data transfer once secure transport is established. I'm studying related topics and read several blogs like how-https-works and how-does-https-work-rsa-encryption-explained/. While it does not describe SSL itself, it should be handy to make sense of why knowing a public key doesn't reveal the contents of a message.
How does a company get a certificate?

CrazyGames features the latest and best free online games. Sure, SSL/TLS uses asymmetric crypto to establish a shared secret (and thus encryption keys for a symmetric encryption algorithm), but the client's public key (if there is one) is never used for encrypting anything in this context.
In SSL communication, public key is used to encrypt private key (session key) and then use symmetric encryption to transfer data (for performance purpose because symmetric encryption is faster than asymmetric encryption) 4) Google’s server decrypts the encrypted data using its private key and gets the session key , and other request data. Any data encrypted with this public key can only be decrypted by Google’s private key which Google doesn’t share with anyone. That text is encrypted by the private key of the CA and can only be decrypted by a public key of CA. A certificate is like something to prove who you are and it also contains a public key for asymmetric encryption. Can't anyone copy the encrypted digital signature of CA and create a fake certificate ?

Public/private smalokalt key encryption is based on modulo arithmetics using prime numbers. I have read the doc, it says session key is generated and transimited What I don't understand is, couldn't a hacker just intercept the public key it sends back to the "customer's browser", and be able to decrypt anything the customer can.
3) The browser then encrypts (1 copy of session key + other request data) with the Google's public key . 1) When you enter the URL , Google’s server gives its public key and certificate (which was signed by GeoTrust) to the Browser. These root-certificates contain the public key of that CA provider which helps decrypt the signature. This certificate is then decrypted with the private key of the website owner and finally, he installs it on the website. Website owner first generates a public key and private key, keeping the private key secret.
Another approach is to use public keys to only decrypt the data and private keys to only encrypt the data. Now, others can only encrypt the data using the public key and that data can only be decrypted by the private key of Jerry. Suppose Jerry generates a private key and public key.
