For further details and troubleshooting, see our guide on paswordless SSH login using SSH keys. ssh-keygen authentication key generation, management and conversion. You need to next extract the public key file. If you’ve already generated a key pair, this will prompt to overwrite them, and those old keys will not work anymore. This guide explains the process of creating CA keys and certificates and uses them to generate SSL/TLS certificates & keys using SSL utilities like OpenSSL and cfssl. Using OpenSSL you can generate several kinds of public/private key pairs. The RSA private key in PEM format (the most common format for X.509 certificates, CSRs and cryptographic keys) can be generated from the command line using the openssl genpkey utility.
