We have added support for RISC-V hardware in our wolfBoot library. The reference example uses the SiFive HiFive1 FE310 board to demonstrate a secure bootloader and firmware upgrade. The HiFive1 is a 32-bit E31 RISC-V core capable of running at 320MHz. It includes 4MB of external flash and 16KB of internal RAM. The wolfBoot library […]

wolfSSL’s embedded SSL/TLS library has included support for TLS 1.3 since early releases of the TLS 1.3 draft. Since then, wolfSSL has remained up-to-date with the TLS 1.3 specification. In this post, the major upgrades of TLS 1.3 from TLS 1.2 are outlined below: TLS 1.3 This protocol is defined in RFC 8446. TLS 1.3 […]

Are you a user of MCU with CryptoCell hardware?  If so, you will be happy to know that wolfSSL recently added support for CryptoCell with wolfCrypt and benchmark examples to the wolfSSL embedded SSL/TLS library! The wolfSSL port supports the following features: SHA-256 AES CBC Elliptic Curve Digital Signature Algorithm (ECDSA) – sign and verify […]

wolfSSL provides many products, services, and support for almost all things TLS and embedded. One of these products provided by wolfSSL is wolfSSH – an SSHv2 server library! wolfSSH is wolfSSL’s own open-source and dual-licensed implementation of the SSHv2 protocol. It’s a server library written in ANSI C and targeted for embedded/RTOS/resource-constrained environments. It’s fast, […]

Benchmark values of the wolfSSL embedded SSL/TLS library running on Xilinx boards, including the ZCU102, have been collected and are up for viewing. Our friends over at Xilinx have a white paper posted that goes into detail about the benchmark values here https://www.xilinx.com/support/documentation/white_papers/wp512-accel-crypto.pdf. This shows how much faster applications can perform secure operations when incorporating […]

author: Daniel Stenberg Whatever we do and whatever we try, no matter how hard we try to test, debug, review and do CI builds it does not change the eternal truth: Nothing gets tested properly until released. We worked hard on fixing bugs in the weeks before we shipped curl 7.65.0. We really did. Yet, […]

It’s common to hear the term asymmetric or symmetric cryptography but what does this actually mean? A brief explanation is that asymmetric cryptography is cryptography that has two keys which is why it is also called public-key cryptography. Both keys in the algorithm are linked to each other in a mathematical way, which allows for […]

wolfBoot is wolfSSL’s own implementation of a secure bootloader that leverages wolfSSL’s underlying wolfCrypt module to provide signature authentication for the running firmware. The role of a secure bootloader is to effectively prevent the loading of malicious or unauthorized firmware on the target. Additionally, wolfBoot provides a fail-safe update mechanism, that can be interrupted at any time, and resumed […]

With the release of wolfSSL 4.0.0, the wolfSSL team has also released a new product: the wolfSSL FIPS Ready library. This product features new, state of the art concepts and technology. In a single sentence, wolfSSL FIPS Ready is a testable and free to download open source embedded SSL/TLS library with support for FIPS validation, […]

As many people know, the OpenSSL project is struggling with FIPS, and their new FIPS release is not expected until December 2020. The version of OpenSSL that supports FIPS goes into End Of Life and is no longer supported in December of 2019. This means that OpenSSL users will not have a supported package for […]
