The wolfSSL implementation of DTLS 1.3 supports Early Data or 0-RTT Data. Early Data is application data that can be sent by the client with the very first ClientHello message. It is also called 0-RTT Data because it requires 0 Round Trip Time before application data can be sent. To utilize Early Data in DTLS […]

We at wolfSSL are continuously improving performance of the wolfCrypt code. Recently we took a look at our AES-GCM on Aarch64 and thought: we can do better. By using the cryptographic instructions built into Aarch64 chips we had already gotten a significant boost over straight C but we saw that we could do more. By […]

wolfEntropy, a software-based entropy source developed by the wolfSSL team, leverages timing jitter variations in memory accesses across various cache levels to generate entropy. It has been available since wolfSSL v5.5.4, and support for Windows has been introduced. This eliminates the need for hardware redesign to incorporate a hardware-based entropy source. The first general purpose […]
