Generate SSL certs easily for Spring Boot apps

Spring Boot Starter ACME

A Spring Boot module that is meant to ease the pain of generating a valid SSL Certificate using the Automatic Certificate Management Environment (ACME) protocol.

This project depends on the acme4j library.

Dependencies

This module depends on having openssl on the PATH to convert the certificate to PKCS12 format.

Usage

1. Add the module to your pom.xml file as a dependency.

2. Build your project.

3. Deploy it to a target machine and point your domain name to the IP address of that machine. LetsEncrypt validates your ownership of the domain by making a callback to the http://your-domain/.well-known/acme-challenge/{token} endpoint exposed by this module.

4. Make sure that your server has openssl available on its $PATH.

5. To activate spring-boot-starter-acme and generate a certificate execute:

sudo java -Dserver.port=80 -Dacme.enabled=true -Dacme.domain-name=<YOUR_DOMAIN_NAME> -Dacme.accept-terms-of-service=true -jar mysecureapp-0.0.1-SNAPSHOT.jar

5. Check your console for a confirmation that the certificate was successfully generated.

6. Stop your application and configure it to make use of the generated certificate:

server.port=443
server.ssl.key-store=keystore.p12
server.ssl.key-store-password=password
server.ssl.keyStoreType=PKCS12

spring-boot-starter-acme's Issues

Support for certificate renewal?

Is there any?
Cheers

Plugin does not support ACME v2

When I tried to run the command below:
java -Dserver.port=80 -Dacme.enabled=true -Dacme.domain-name=localhost -Dacme.accept-terms-of-service=true -jar myapplication.jar

I got this error:

Caused by: org.shredzone.acme4j.exception.AcmeUnauthorizedException: Account creation on ACMEv1 is disabled. Please upgrade your ACME client to a version that supports ACMEv2 / RFC 8555.
