Simple setup to create your own CA This code sets up a simple Certificate Authority (CA) for generating SSL/TLS certificates:

1. It initializes the CA setup by executing bootstrap.sh, which sets up the necessary directory structure and configuration files.
2. It creates the CA root certificate chain by running create_cachain.sh.
3. It generates a server certificate for the current machine (identified by hostname -f) using gen_server_cert.sh. This script generates a private key, a certificate signing request (CSR), and then signs the CSR to create the server certificate.
4. Finally, it exports the generated certificate and its private key to the specified destination folder (/home in this case) using export.sh. If the -k option is provided, it also exports the private key.

echo "Welcome" > passfile
bash bootstrap.sh

bash create_cachain.sh
bash gen_server_cert.sh `hostname -f`
bash export.sh -i intermediate -c `hostname -f` -d /home -k
