SSH key

Generate

To generate ssh key with ed25519 use:

$ ssh-keygen -t ed25519 -C "<email>"

If you want to use rsa for reasons like legacy system, then do it with at least 4096 bits:

$ ssh-keygen -t rsa -b 4096 -C "<email>"

Why choose ed25519 instead of rsa?

rsa concidered less secure and ed25519 keys are shorter for same level of security, which makes them faster.
