I am using ssh every single day and I know why I need to use it. But, I don’t know how does it work. And my curiosity starts to begin. I found a very nice article on DO. But, I still want an explanation via video. Then I go through YouTube and found out the following useful videos…

How Secure Shell Works (SSH) – Computerphile this one explain everything, including why we need ssh and how does it work. From that explanation, I got another reference video of that channel which is SHA: Secure Hashing Algorithm – Computerphile which explains more detail of SHA which was used by SSH.

Those explain pretty well to me and I understand how does shh work ?
