Is id_rsa public or private key?
When generating a key, you’ll get two files: id_rsa (private key) and id_rsa. pub (public key). As their names suggest, the private key should be kept secret and the public key can be published to the public.
How do I use SSH keys on Mac?
Creating a SSH Public Key on OSX
- Enter the following command in the Terminal window: ssh-keygen -t ed25519.
- Press the ENTER key to accept the default location. The ssh-keygen utility prompts you for a passphrase.
- Type in a passphrase. You can also hit the ENTER key to accept the default (no passphrase).
What are SSH keys used for?
An SSH key is an access credential for the SSH (secure shell) network protocol. This authenticated and encrypted secure network protocol is used for remote communication between machines on an unsecured open network. SSH is used for remote file transfer, network management, and remote operating system access.
What do I do with a private SSH key?
You keep the private key a secret and store it on the computer you use to connect to the remote system. Conceivably, you can share the public key with anyone without compromising the private key; you store it on the remote system in a . ssh/authorized_keys directory.
Where do I generate SSH keys?
1. Create a Key Pair on Your Computer
- Open a terminal window. At the shell prompt, type the following command: ssh-keygen -t rsa.
- The ssh-keygen program will prompt you for the location of the key file.
- Note the location to which your public and private key were saved; they will be required in a subsequent step.
If someone has accessed your private key it they have the ability to access any device or encrypted file that was protected with your public key. It also means that they can sign things on your behalf it is VERY bad if someone has gained access to your private key.
How do I pass a private key using ssh?

How to view your SSH keys in Linux, macOS and Windows?
Remember id_rsa is the private key and id_rsa.pub is the public key. And that’s all there is to viewing your SSH public and private keys on Linux, macOS, and Windows.
How does SSH protocol 2 support DSA and RSA?
Protocol 2 supports both RSA and DSA keys; protocol 1 only supports RSA keys. For both protocols, each host has a host-specific key, normally 2048 bits, used to identify the host. Forward security for protocol 1 is provided through an additional server key, normally 768 bits, generated when the server starts.
What kind of SSH key does Joyent use?
Joyent recommends RSA keys because the node-manta CLI programs work with RSA keys both locally and with the ssh agent. DSA keys will work only if the private key is on the same system as the CLI, and not password-protected.
