If you have existing keys you want to keep, enter a new file name. The default directory and file for key storage is /home//.ssh/id_rsa. Next, the program asks where to save the file: The output prints out a message, indicating the command ran successfully. The following command starts the key generator: ssh-keygen Change the permissions to 700: chmod 700 ~/.sshДҐ. Create the directory using the mkdir command for storing the new key pair: mkdir ~/.sshД¤. If there are no existing keys, the output indicates the folder does not exist:ДЈ. However, stating a new name for the keys saves them to different files.

Generating new keys overwrites the current ones by default. If there are keys already, the output shows the directory contents: Check for existing keys with: ls -l ~/.ssh/id*

For automation purposes, key management software and practices apply since the private key stays unprotected otherwise. Adding a passphrase to encrypt the private key adds a layer of security good enough for most user-based cases. The model assumes the private key is secured.

The server allows access to anyone who proves the ownership of the corresponding private key. The server stores and marks the public key as approved.Д¤. Add the corresponding public key to the server.ДЈ.
