The certusine package provides an ACME client.

Features

• Uses acme4j internally for strong RFC compliance.
• Exclusively uses the DNS-01 ACME challenge type for ease of integration with infrastructure without having to set up insecure web servers.
• A small, easily auditable codebase with a heavy use of modularity for correctness.
• Exposes a service provider API for integrating with new DNS APIs.
• Exposes a service provider API for implementing new types of certificate outputs.
• Supports Vultr DNS.
• Supports Gandi LiveDNS.
• Supports writing certificates to looseleaf servers.
• Heavily instrumented with OpenTelemetry for reliable service monitoring.
• An extensive automated test suite with high coverage.
• A small footprint; the client is designed to run in tiny 16-32mb JVM heap configurations.

• OSGi-ready.
• JPMS-ready.
• ISC license.
