View ChangeLog


  • Industry-leading native crypto
  • Java JNI wrapper
  • Java JCE Provider
  • Tested against multiple JDK implementations


  • Allows applications to have control over their crypto
  • Gain portability of native wolfSSL and wolfCrypt libraries


  • Eliminates need to write custom JNI
  • Based on industry-leading wolfSSL


Platform and Language Support

The native wolfSSL library is built for maximum portability and is generally very easy to compile on new platforms.  If your desired platform is not listed under the supported operating environments, please contact us.

Commercial Support

Support packages for wolfSSL and wolfCrypt JNI/JCE are available on an annual basis directly from wolfSSL.  With three different package options, you can compare them side-by-side and choose the package that best fits your specific needs.  Please see our Support Packages page for more details or contact us with any questions.

JDK Support

wolfCrypt JNI and JCE have been tested against multiple JDK implementations including Oracle JDK, OpenJDK, and Android’s JDK implementation.

Ships with Signed JAR Files

Oracle JDK requires JCE providers to be signed.  This signed JAR is then authenticated at runtime.  wolfCrypt JNI includes JAR files that have been pre-signed by wolfSSL to get you up and running quickly!

FIPS Support

Do you need FIPS 140-3? The wolfCrypt JNI and JCE Provider can sit on top of the FIPS 140-3 validated wolfCrypt library. Learn more about our FIPS 140-3 validation!

Algorithm Expansion

wolfCrypt JNI currently includes a subset of algorithm functionality found in the native wolfCrypt C library.  If you are interested in an algorithm not currently supported in the JNI/JCE wrapper, let us know at
