wolfSSL has support for the new DTLS 1.3 protocol. You can learn more about this protocol in our “What’s new in DTLS 1.3” blog post (https://www.wolfssl.com/whats-new-dtls-1-3/). Using DTLS 1.3 in wolfSSL is almost as easy as using DTLS 1.2! Client implementations only need to change their existing wolfDTLSv1_2_client_method() calls into wolfDTLSv1_3_client_method(). If you are using […]

The DTLS 1.3 standard has recently been published in April 2022 in RFC 9147. It features many improvements and additions to increase security and efficiency of the DTLS protocol. At wolfSSL, we like to be very quick adopters of new standards which is why initial support for DTLS 1.3 was merged in June and appeared […]

wolfBoot is known for being the universal secure bootloader for all types of embedded systems. While initially targeting 32-bit microcontrollers, wolfBoot has grown into a full framework to implement secure boot solutions on a wide range of different systems and architectures. This is mostly due to wolfBoot modularity and flexibility, which makes our solution easy […]

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 […]
