¶ FAQ
¶ Generate an SSH key pair
If you do not have an existing SSH key pair, generate a new one:
-
Open a terminal.
-
Run ssh-keygen -t followed by the key type and an optional comment. This comment is included in the .pub file that's created. You may want to use an email address for the comment.
For example, for ED25519:
ssh-keygen -t ed25519 -C "<comment>"
For 2048-bit RSA:
ssh-keygen -t rsa -b 2048 -C "<comment>"
- Press Enter. Output similar to the following is displayed:
Generating public/private ed25519 key pair.
Enter file in which to save the key (/home/user/.ssh/id_ed25519):
- Accept the suggested filename and directory, unless you are generating a deploy key or want to save in a specific directory where you store other keys.
