The record

Purpose: SignServer is a server-side platform for digitally signing code, documents, and timestamps.
Centralized signing: It centrally stores and manages signing keys and supports multiple signing use cases in one installation.
Signing use cases: The site lists code, container, firmware, document, and timestamp signing, including IoT and DevOps use cases.
Automation: SignServer can integrate with CI/CD pipelines, firmware build processes, document workflow engines, identity platforms, and other business applications through standard interfaces.
Deployment: Community can be downloaded as a Docker container, Helm chart, source code, or release from GitHub, and is also listed on SourceForge.
Key protection: The maker recommends storing signing keys in a Hardware Security Module; secure-file storage is described as suitable only for testing and prototyping.
Community production limit: Community Edition is not intended for production and lacks audit, compliance, SLA, high availability, and security capabilities needed for production workloads.
Enterprise support: Enterprise offers professional support with an SLA, timely security updates, and maintenance.
Interfaces: The edition comparison lists SOAP, HTTP, REST, and the SignClient command-line interface; Community REST support does not include all endpoints.
Signing formats: The edition comparison lists code signing for CMS, OpenPGP, Debian, and Java in Community, with Microsoft and Android code signing listed for Enterprise and Cloud.
Integrations: The comparison lists integration and secure automatic certificate renewal with CA/EJBCA, and the maker describes integration with third-party applications through standard interfaces.
License: SignServer Community is released under LGPL V2.1 or later.
Download verification: The maker recommends verifying downloads with SHA-512 hashes from GitHub or OpenPGP signatures from SignServer Keys.
History: The first version of SignServer was released by PrimeKey in 2005, and the Enterprise edition was released in 2012.
