Common OpenSSL Commands with Keys and Certificates
Generate RSA private key with certificate in a single command
Jul 09, 2019 If the Private Key key file is lost, you’ll need to reissue your Certificate. Can I generate a new Private Key for my Certificate if I lose the old one? You can generate a new private key and CSR, or use the automatic CSR and key generation during Certificate reissue (this option is available for all Certificates except for the Multi. The corresponding public key, which is available to everyone, is used to verify this signature. The secrecy of the private key must be maintained because the framework falls apart after the private key is compromised. Given enough time and resources, a public/private key pair can be compromised, that is, the private key can be discovered. The private key does not need to be there unless you are going to use it to sign a certificate containing another public key. When you are sending over your public key, instead send over an entire certificate (except for the private key), signed using the associated CA private key. In case you travel and can’t carry your laptop with you, just keep your private key on a USB stick and attach it to your physical keychain. Your server will be much safer this way.
