Common OpenSSL Commands with Keys and Certificates

SSL Info

Generate RSA private key with certificate in a single command

openssl req -x509 -newkey rsa:4096 -sha256 -keyout example.key -out example.crt -subj "/CN=example.com" -days 3650 -passout pass:foobar

Generate Certificate Signing Request (CSR) from private key with passphrase

openssl x509 -x509toreq -in example.crt -out example.csr -signkey example.key -passin pass:foobar

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
