rsa - how does public key cryptography work -

Regarding RSA, I think Alice can make a public and a private key combination, and then send the public key to it.

Bob. And after that Bob can encrypt something by using the public key, and Alice will use the public and private key combo to decrypt it.

However, how can Alice be sent to Bob? How would Bob decrypt it? I will ask because I am curious that when I log in to my banking site, my bank sends me data like online details, how does my browser decrypt that information? I do not have a private key.

Simple, you need a key.

SSL / TLS resolves this problem by creating a symmetric session key during connection installation. Public key cryptography is used to establish this session key, which is used for bi-directional data communication
