Features of SignServer Enterprise

PrimeKey SignServer is a versatile digital signature software that enables a wide range of digital signature use cases and formats. Server-side digital signatures give maximum control and security, allowing your users and applications to conveniently sign code, PDF documents, XML, and more.


Versatile signing platform

The SignServer platform covers all your signing use cases in one solution, including standard document signing, eIDAS advanced signing and seal, code signing for multiple formats, timestamping services and ICAO ePassport signing. Avoid managing a myriad of signing solutions and centralize all your signature processes in this multitenant solution and improve on security policy compliance. 


Security by design

Server-side signature solutions give maximum control and security and allow you to leverage your hardware security module (HSM) investment in the best way. Signature keys are generated and used for signing in your HSM. SignServer supports most HSMs on the market - and both short-lived keys, and keys or certificates with a longer lifecycle. In addition, the software signs all audit logs for traceability and audit requirements.


Flexible integrations

SignServer is designed to perform automated signatures and cryptographic operations and integrates well with your document workflow engine, CI/CD pipeline tool, identity and authorization platform, or any other business application via standard interfaces. See also PKI and Signature Services for Microservices and DevOps Environments. 


High performance and high availability

SignServer scales indefinitely by adding an additional instance of the software and best-practice configurations are available for all the different deployment options.
