BouncyHSM
A developer-friendly software simulator for HSM and smartcard with PKCS#11, REST API, and web UI for testing cryptographic applications.
What is BouncyHSM?
Bouncy Hsm is a software simulator for Hardware Security Modules (HSM) and smart cards that provides a PKCS#11 interface, REST API, and web UI. It enables developers to test and develop applications that rely on cryptographic hardware tokens without needing physical devices. The project solves the problem of unreliable or complex HSM simulators by offering a developer-friendly, cross-platform alternative.
Developers and testers working on applications that use PKCS#11 interfaces for cryptographic operations, such as those building secure authentication systems, digital signature solutions, or certificate management tools.
Developers choose Bouncy Hsm for its broad algorithm support, ease of use via web and REST interfaces, and reliability as an alternative to SoftHSMv2. Its dependency-free native library and cross-platform compatibility reduce setup complexity and ensure consistent testing environments.
Overview
Bouncy Hsm is a software simulator of HSM and smartcard simulator with HTML UI, REST API and PKCS#11 interface.
Use Cases
Best For
- Testing PKCS#11-dependent applications without physical HSMs
