The Utimaco CryptoServer SDK is a professional development environment for Utimaco Hardware Security Modules (HSMs), enabling the creation of customized firmware applications such as proprietary algorithms, custom key derivation procedures, and complex protocols. It provides full control over firmware functionality, supports standard programming languages, and includes tools for efficient testing and debugging. The SDK allows integration with common development environments and supports a wide range of cryptographic algorithms, including RSA, ECDSA, AES, and SHA. It is designed for industries requiring high security, such as banking, healthcare, and automotive, and supports compliance with standards like FIPS 140-2. The SDK also includes a software simulator for testing and validation without hardware.
