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

Demonstrates chart generation on both server side (top chart) using node.js and client side (bottom chart).

Note: For the purpose of this example and not having node.js available servers side, chart.svg has been pre generated using instructions for this project:

npm install
node index.js > chart.svg
