You have your private key for decoding what I send you encrypted with the public key you sent me.
And I have my private key for decoding what you send me. That's 4 keys.
However it's pretty outdated and has serious flaws. Noted at https://blog.whiteout.io/2015/02/25/pgp-theres-life-in-the-old-dog-yet/
I was reading about PGP, have a question in mind.
I understand that I need to use the receiver Public key to send a encrypted email, so that he can open it with his private key.
To do this process dose both people need to create their public key first and share between them in-order to start the communication or I can find the public key of the person just simply using his email ID and send him an encrypted email and ask him to create a private key to open it.
I might be asking a very stupid question, but if you can clarify that would be much appreciated.
