Execute the command:
ssh-keygen
By default, recent versions of ssh-keygen will create a 3072-bit RSA key pair, which is
secure enough for most use cases (you may optionally pass in the -b 4096 flag to
create a larger 4096-bit key).
After entering the command, you should see the following output:
Generating public/private rsa key pair.
Enter file in which to save the key (/your_home/.ssh/id_rsa):
Press enter to save the key pair into the .ssh/ subdirectory in your home directory, or specify an alternate path.
