How does HTTPS work? What's a CA? What's a self-signed Certificate?

6 років тому

Is HTTPS really that difficult? Do I need to know crypto theory and a lot of math to understand it? You don't! This video explains how HTTPS works in very simple terms. It will touch upon encryption and digital signatures, as well as explaining what a trusted Certificate Authority is and what a self-signed certificate is.
We will build upon this knowledge in upcoming videos, when we plan to issue a self-signed certificate to secure a microservice app in a testing environment.
You no longer have an excuse to say HTTPS is too complex. Because this video simplifies all the concepts in less than 12 minutes.

This 11 min video was more educating then an entire course of pluralsight on How HTTPS works. Thank you for this.

I would like to add, for clarity, that: 1. A message encrypted with a public key is used for secrecy - The message can only be decrypted with the corresponding private key, but you cannot verify who the owner is. 2. A message encrypted with a private key is used for authentication - The message owner can be verified if you know the corresponding public key, but is not secret. - This is why a web browsers have a record of public keys for CA Authorities - so they can verify that a "public key certificate" is signed by the a real CA Authority

so you mean to say google exposes both public key and private key? then the attackers will be able to decrypt right?

@jagan1957 4 роки тому

Wow a lot of concepts in a nutshell.... Very effective!! Just one suggestion to add - The CA certificate which is signed by the CA authority statically resides in the computer either through browser or - If we have our own CA certificate, then we implant it into the browser by copying into it. So practically we can also mention in the video where the CA certificate is stored in each case which is the only missing part according to me. Thanks a lot for the video again!
