Step 1 Create the RSA Key Pair The first step is to create a key pair on the client machine (usually your computer): ssh-keygen By default 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: OutputGenerating public/private rsa key pair....
