Generating SSH keys¶
SSH keys serve as a way to identify users to an SSH server without involving passwords.
In order to generate a NEW key follow these steps:
- Check for existing SSH keys on your computer.
$ ls -la ~/.ssh # Lists the files in your .ssh directory , if they exist # By default, the filenames of the public keys are one of the following: # # id_dsa.pub # id_ecdsa.pub # id_ed25519.pub # id_rsa.pub
- An SSH key pair can be generated by running the
$ mkdir ~/.ssh $ chmod 700 ~/.ssh $ ssh-keygen -t rsa -b 4096 -C "email@example.com" Generating public/private rsa key pair. Enter file in which to save the key (/home/username/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/username/.ssh/id_rsa. Your public key has been saved in /home/username/.ssh/id_rsa.pub. The key fingerprint is: dd:15:ee:24:20:14:11:01:b8:72:a2:0f:99:4c:79:7f firstname.lastname@example.org The key's randomart image is: +--[RSA 4096]---+ | ..oB=. . | | . . . . . | | . . . + | | oo.o . . = | |o+.+. S . . . | |=. . E | | o . | | . | | | +-----------------+
