Openssl rsa -in server.key -out server-nopassphrase.key Single command to generate a key and certificate Earlier we covered the steps involved with creating a self-signed cert: generating a key, creating a certificate signing request, and signing the request with the same key. Jul 09, 2019  Can I generate a new Private Key for my Certificate if I lose the old one? Normally, the CSR/RSA Private Key pairs on Linux-based operating systems are generated using the OpenSSL cryptographic engine, and saved as files with.

SSL certificates are cool. They will be used more and more. This tutorial should be used only on development and/or test environments!

For a production environment please use the already trusted Certificate Authorities (CAs).

This key & certificate will be used to sign other self signed certificates. That will be covered in another tutorial.

here's a video:

Generate the CA key

You'll be prompted to enter a password.

openssl genrsa -des3 -out myCA.key 2048

Generate the Certificate

Openssl Generate Private Key Certificate Request

openssl req -x509 -new -nodes -key myCA.key -sha256 -days 3650 -out myCA.pem

3650 means that it will be valid for 10 years. Yes!

You can optionally remove the password from the key. For development purposes it would most likely be OK.

Make a backup of the original key

Linux/Mac: cp myCA.key myCA.key.with_pwd
Windows: copy myCA.key myCA.key.with_pwd


Export the CA key without a password

This is useful so you don't have to keep track of the password and/or use a script to sign self-signed SSL certificates.

openssl rsa -in myCA.key.with_pwd -out myCA.key

Convert the CA certificate from .PEM to .CRT format

openssl x509 -outform der -in myCA.pem -out myCA.crt
