Be aware that ssh-keygen by default uses the old RSA alchorithm. It's advised to switch to the newer ED25519. You can generate a more secure keypair with this command: _ssh-keygen -o -a 100 -t ed25519_ Here with -o we specify to ssh-keygen that we want the new key format. -a sets the number of encryption rounds to 100 to make it much harder to brute force. Finally with -t we set the format to ed25519. The default path is ~/.ssh/id_ed25519 for the key and ~/.ssh/id_ed25519.pub for the public key. Stay safe! :-)

Unless you're a "stable" distro user, openssh has been using new format for all keys since v7.8. In fact, to use old PEM format you would have to explicitly specify it with -m and -o is not a valid option anymore. Also, ed25519 uses new format only.

Although I haven't watched the entire Video but: - The plus point for the video here is that I use relatively standard language, even though I'm not fluent in English. Because of my poor English, I had to use subtitles for the Video and it was translated into my language very properly and fully. - Minus point in this Video is a quick guide. This Video content is for beginners to learn about SSH. Unfortunately. *** But this is my own comment. Your video is only 8 minutes, but I have to watch it for nearly 2 hours. _ * Thanks anyway for sharing it for free. And I clicked "Like" for you. Thanks you

Very clear video. I find that ssh key stuff sometimes is hard to understand for some. Your video does an excellent job in explaining all.

I also was confused by public and private keys when I read about them the first time. Everything becomes clear after you use it for some time

I see you copy the key to the remote server from the client side. What if you create the keys from the server side. Do you still have to add the key to the server itself since the key already created there? Or in the case I am talking about you just copy the private key to the client (Client is the one to be used afterwards for remote access. Its just that installation of keys happening from the server side). PS Upon installation keys go different directory than the one they are created? Thank you

where are you supposed to create the ssh keys(both) from ? is it the client computer or remote computer

Very helpful, thank you. My biggest issue is that every time I copied my public key to the server, it would also copy my client username, and the linux machine would think that that was part of the key, so it would always lock me out! Lol

If I have a server with key-based login only and I want access from yet another machine, how can I add the other key? I can't just use ssh-copy-id because I can't authenticate without the key from the first machine
