Generating an SSH Key on Windows using PuTTYgen
1. Download and install the full PuTTY installer package or the standalone PuTTYgen binary.
2. Open Putty Key Generator (PuTTYgen) to generate a new SSH key.
3. Select RSA with a key size of 2048 and select Generate.
4. Save the public key and private key in a secure location after they have been generated.
5. Copy the complete contents of the SSH key file from the Public key for pasting into OpenSSH authorized_keys file box to your clipboard. The SSH key starts with ssh-rsa and ends with == rsa-key-<date>, for example:
ssh-rsa AbCdEfGh1234AbCdEfGh== rsa-key-20200911
Generating an SSH Key on macOS/Linux using ssh-keygen
1. Open the macOS/Linux Terminal through the Launcher or by navigating to the Finder > Applications > Utilities section (macOS).
2. Use the ssh-keygen command to generate a new SSH Key:
ssh-keygen -t rsa
3. Either use the default file name or enter a file name of your choice and optionally add a passphrase.
4. View the contents of the public SSH key file. Assuming the file name was not changed:
5. Copy the complete contents of the SSH key file from the Terminal window to your clipboard. The SSH key starts with ssh-rsa and ends with username@machine, for example:
ssh-rsa AbCdEfGh1234AbCdEfGh admin@computer
