wolfSSL JNI (Wrapper)
For Java developers that want to leverage the industry-leading wolfSSL SSL/TLS implementation (formerly CyaSSL) for secure communication, wolfSSL JNI provides an interface to give Java applications support for the current SSL/TLS standards up to TLS 1.2 and DTLS 1.2.
wolfSSL JNI, backed by wolfSSL, provides current industry protocol standards, offers progressive ciphers, and gives applications flexibility over controlling their secure connection.
Existing Java implementations lack support for DTLS. wolfSSL JNI provides full DTLS 1.0 and 1.2 support.
- Up to TLS 1.2 and DTLS 1.2
- Full client and server support
- Progressive list of supported ciphers
- Key and Certificate generation
- OCSP, CRL support
- Support Available
- Several callbacks make integration into existing applications easy
- Gives applications complete control over secure communication
- Eliminates need to write custom JNI
- Based on industry-leading wolfSSL
- Includes support for Android NDK
Platform and Language Support
wolfSSL (formerly CyaSSL) 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.
wolfSSL supports the C programming language as a primary interface. It also supports several other host languages, including Java, PHP, Perl, and Python (through a swig interface). If you have interest in using wolfSSL in another programming language that it does not currently supported, please contact us.
Support packages for wolfSSL 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.
If you would like more detailed information about RAM usage, please contact us for the wolfSSL Resource Use document.
LeanPSK - wolfSSL recently implemented a set of build options for wolfSSL which enable the library to be built in as little as 20kB! This build configuration requires the use of pre-shared keys (PSK). Contact us for more details about this build.
