wolfSSL 4.4.0 introduces new ChaCha20/Poly1305 API’s for AEAD to allow “chunked” updates of data followed by a final calculation for the authentication tag. This uses the same “Init”, “Update”, “Final” conventions commonly available with our hash algorithms. New API’s are available by default and can be disabled using: NO_CHACHAPOLY_AEAD_IUF. wc_ChaCha20Poly1305_CheckTag wc_ChaCha20Poly1305_Init wc_ChaCha20Poly1305_UpdateAad wc_ChaCha20Poly1305_UpdateData wc_ChaCha20Poly1305_Final wc_Poly1305_Pad […]

Building Qt with wolfSSL
wolfSSL 4.4.0 adds support for building Qt 5.12 and 5.13 against the wolfSSL embedded SSL/TLS library instead of the default OpenSSL backend! Using wolfSSL as a TLS provider in Qt can have many advantages, depending on application and industry. Some of these may include: Progressive TLS protocol support (up to TLS 1.3) Smaller footprint size […]
Read MoreMore TagSSL/TLS in Qt: Introduction to wolfSSL
Don’t miss this hot topic! wolfSSL Chris Conlon, Engineering Manager presents: https://resources.qt.io/videos/ssl-tls-in-qt-introduction-to-wolfssl-wolfssl-qt-virtual-tech-con-2020 Qt has traditionally used OpenSSL as the provider for SSL/TLS in Qt Network for secure network communications. Qt developers who are looking for a lightweight, progressive, and well-tested SSL/TLS implementation will be happy to learn how Qt can be used with the wolfSSL […]
Read MoreMore TagwolfSSH SSH Agent Support
wolfSSL Inc is adding support for the SSH-AGENT authentication to wolfSSH. The SSH-AGENT allows one to log in through multiple machines with a single private key on one’s local terminal. A good example is logging onto a test server and then accessing GitHub with git which uses SSH. Git will ask SSH on the test […]

Did you know that the wolfSSL embedded SSL/TLS library supports the Renesas Trusted Secure IP Driver (TSIP) and has been tested on the Renesas RX65N platform? Using the TSIP driver, wolfSSL can offload supported cryptographic and TLS operations to the underlying Renesas hardware for increased performance. wolfSSL has been integrated with the following TSIP capabilities: […]
Read MoreMore TagDistribution of Crypto Operations
wolfSSL is developing a library to handle the location of where crypto operations run amongst multiple cores. For large systems that have many sign/verify operations happening at once this library would be able to distribute those sign/verify requests based on a user’s input. In addition to managing where the operation runs it can be used […]
Read MoreMore TagCrypto Validation with wolfACVP
The new Automated Cryptographic Validation Protocol is the successor to the two decade old CAVP system from NIST. The ACVP system is intended to alleviate the manual steps of the older process, creating a more efficient and effective method for cryptographic algorithm testing and validation. The project started in 2016 and is currently executing the […]
Read MoreMore TagFuzzing for wolfSSL
This post was written by Guido Vranken and originally published on his blog (May 13, 2020). Larry Stefonic of wolfSSL contacted me after he’d noticed my project for fuzzing cryptographic libraries called Cryptofuzz. We agreed that I would write a Cryptofuzz module for wolfSSL. I activated the wolfSSL module for Cryptofuzz on Google’s OSS-Fuzz, where it has […]
Read MoreMore TagwolfSSL Use With Hexagon Toolchain
The Hexagon SDK is used for building code to run on DSP processors. Use of the Hexagon toolchain to offload ECC verify operations has been added to wolfSSL. This can free up the main CPU for other operations or lead to future optimizations with HVX on some algorithms that use vector operations. The Makefile for […]
Read MoreMore TagTop Ten Things you should know about Secure Boot
At wolfSSL, we have been developing secure boot solutions with customers for many years, and more recently we have released wolfBoot, a secure bootloader designed for embedded systems. wolfBoot provides reliable support to remote firmware updates on a wide range of devices, supporting the most common architectures (ARM Cortex-M, ARM Cortex-A, RISC-V RV32). wolfBoot supports […]
