The Utimaco SecurityServer Simulator is a fully functional software version of the Utimaco SecurityServer Hardware Security Module (HSM) designed for evaluation, development, and integration testing without requiring hardware purchase or installation. It is available for Windows and Linux operating systems and supports standardized cryptographic APIs such as PKCS#11, CSP/CNG/SQLEKM, and JCE, enabling integration with third-party applications. The simulator allows users to test configurations, application settings, and high-availability scenarios, and it aids R&D teams and developers using the Utimaco CryptoServer Software Development Kit (SDK) for firmware development and validation. It provides a cost-effective solution for evaluating HSM features and functionalities in a virtual environment.
