Activate SSL via Lets encrypt

[Atoxien]

Dear community, dear creator,

I use the PDF tool with access to a public server. But how can I install SSL via Lets Encrypt? Don't want to use a self-signed certificate as it would be a Lets Encrypt certificate.

Is there a way to integrate this and make it only accessible via https?

Import Certificate into a Keystore:

You need to convert the PEM-formatted certificate and private key into a PKCS12 keystore. This can be done with OpenSSL:

openssl pkcs12 -export -in /etc/letsencrypt/live/yourdomain.com/fullchain.pem -inkey /etc/letsencrypt/live/yourdomain.com/privkey.pem -out keystore.p12 -name yourdomain -CAfile /etc/letsencrypt/live/yourdomain.com/chain.pem -caname root

Configure Spring Boot:

Enter the path and password information in your application.properties:

# Server port to run the application on HTTPS
server.port=8443

# SSL key-store configuration
server.ssl.key-store=classpath:keystore.p12
server.ssl.key-store-password=yourkeystorepassword
server.ssl.key-store-type=PKCS12
server.ssl.key-alias=yourdomain

# Require SSL
server.ssl.enabled=true

Replace yourkeystorepassword with your keystore password and yourdomain with the alias you used during the export.

I'm not sure if it will work, but you can test it.
