wolfCrypt JCE Provider and JNI Wrapper 1.5.0 Now Available

Version 1.5.0 of the wolfCrypt JCE Provider and JNI wrapper is now available for download!

wolfCrypt JNI/JCE provide Java-based applications with an easy way to use the native wolfCrypt cryptography library. The thin JNI wrapper can be used for direct JNI calls into native wolfCrypt, or the JCE provider (wolfJCE) can be registered as a Java Security provider for seamless integration underneath the Java Security API. wolfCrypt JNI/JCE can work with wolfCrypt FIPS 140-2 (and upcoming 140-3) as well!

Release 1.5.0 of wolfCrypt JNI has bug fixes and new features including:

  • Add build compatibility for Java 7 (PR 38)
  • Add support for “SHA” algorithm string in wolfJCE (PR 39)
  • Add rpm package support (PR 40)
  • Add wolfJCE MessageDigest.clone() support (PR 41)
  • Improve error checking of native Md5 API calls (PR 41)
  • Add unit tests for com.wolfssl.wolfcrypt.Md5 (PR 41)

Version 1.5.0 can be downloaded from the wolfSSL download page, and an updated version of the wolfCrypt JNI/JCE User Manual can be found here. For any questions, or to get help using wolfSSL in your product or projects, contact us at facts@wolfssl.com.

Announcing New Capabilities in wolfSentry

As wolfSentry gets ever closer to its first production release, we are introducing some exciting new capabilities, among them:

  • Mature dynamic rule management, with automatic peer tracking, penalty boxing, O(1) release from penalty box, and realtime-safe (O(1)) limits on resource usage.
  • Robust support in the configuration file and public API for user-defined data (key-value pairs) with freeform JSON values, to arbitrary (user-limited) depth, with a fully integrated API for processing and exporting JSON in DOM (random-access) mode.
  • An API for setting user-defined configuration nodes as read-only.
  • Improvements and extensions to the API for use by user plugins (action handlers) streamlining typical use cases involving dynamic rule insertion and update.
  • Added examples/notification-demo/log_server
    • A standalone web server demonstrating HTTPS with dynamic insertion of limited-lifespan wolfSentry rules blocking (penalty boxing) abusive peers.
    • Mutual authentication using TLS, role-based authorizations pivoting on client certificate issuer (certificate authority), and wolfSentry event log retrieval, as a dynamically generated JSON array.

All of these and more are featured in wolfSentry preview release 7. For more details, clone wolfSentry from https://github.com/wolfSSL/wolfsentry, review ChangeLog.md and README.md, and “make test”.  For questions or help integrating wolfSentry into your project, contact us at facts@wolfssl.com!

wolfSSL running on Xilinx Versal Hardware Encryption

Our Xilinx Versaldemo shows wolfSSL making calls to Xilinx hardened crypto, doing both basic unit tests and benchmarking with it. Xilinx hardened crypto is accelerated crypto operations (SHA3-384 / AES-GCM / RSA / ECDSA) available on Ultrascale+ devices and is available for use with the latest and greatest Versal boards. wolfSSL makes these calls using the API from Xilinx’s XilSecure library (https://github.com/Xilinx/embeddedsw/tree/master/lib/sw_services/xilsecure) and with the addition of Versal there was minor changes to the existing calls to make use of the new features available (ECC / RNG / AES-GCM with AAD). Benchmark numbers are being fine tuned but you can see well over a Gigabyte per second with AES-GCM operations in the demo and improvements in performance of RSA, ECDSA, and SHA3-384 over software only implementations.

A previous white paper going into the setup and use of wolfSSL on older Ultrascale+ devices with Xilinx hardened crypto can be found here (https://docs.xilinx.com/v/u/en-US/wp512-accel-crypto).

wolfSSL TriCore HSM Support

The Infineon Tricore TC2xx and the new TC3xx series chips are popular chips among safety and security critical applications. As the name implies, these chips come with multiple CPU cores to meet the demands of real time computing, however some variants come with a built in HSM core that is an ARM Cortex M3 operating at a frequency of 100MHz, 96KB RAM, MPU and offers a few useful secure applications.

  1. Secure boot
  2. Shared memory bridge module with “Firewall” functionality
  3. Debug support with authentication
  4. Secure data storage and logging
  5. 1KB shared cryptography memory
  6. Configurable OTP and HSM exclusive flash sections
  7. Hardware cryptography (AES, Hash, PKC, TRNG)
  8. Immobilizer (theft protection)
  9. Secure flash loading

We are excited to announce that we have ported wolfCrypt to the TriCore HSM. This will extend the HSM functionality beyond the hardware cryptography support to include the full wolfCrypt suite in the HSM environment. This adds useful features such as:

  2. ECDSA-384
  3. ECC
  4. RSA (2048/3072/4096)
  5. SHA-384/512
  6. NIST Compliant DRBG (with HW TRNG seed)


  • Built and tested using arm-none-eabi-gcc 12.2 toolchain
  • Executed on a TC3XX HSM module with -O2 optimizations at clock of 100Mhz
  • Verified heap-only as well as stack-only usage
  • Benchmarks executed with a 10ms timer
