This script generates self-signed certificates for a given domain into a given direcory. It is based on the following tutorial: How to Create Self-Signed Certificates using OpenSSL

./openssl.sh -d <domain-name> -p <directory>

This will create a certificate authority (CA) in <directory>/CA, a certificate signing request CSR and the following certificates and keys into <directory>/<domain-name>:

• privkey.pem: the private key
• cert.pem: the intermediate certificate
• fullchain.pem: the full chain
