OpenSSH Keys (UNIX)

Creating Your Own Key

To generate a new keypair of your public and private key, use the ssh-keygen tool:

local $ ssh-keygen -t ed25519 -C username@organization.example.com' -f additional_key

Note

Enter a strong passphrase for securing your private key.

By default, your private key is saved to the id_rsa file in the .ssh directory and your public key is saved to the id_rsa.pub file.
