SignServer is a server-side application, capable of creating digital signatures. It supports different types and formats of digital signatures through extendable architecture. Operations regarding/related to ALI Cryptographical operations cryptography are typically carried out in a Hardware Security Module (HSM) or using software key stores. The organization can keep track of all usages of the signing keys.
CryptoServer is a hardware security module, developed by Utimaco IS GmbH. It is a physically protected specialized computer unit, designed to perform sensitive cryptographic tasks and to securely manage, as well as store, cryptographic keys and data. It can be used as a universal, independent security component for heterogeneous computer systems.
