At wolfSSL, we are ensuring that embedded systems, IoT devices, and high-performance computing platforms benefit from the fastest and most secure cryptographic solutions available. Leveraging the available Xilinx hardware acceleration allows for high-speed encryption, decryption, and hashing with minimal CPU overhead, making it ideal for applications in aerospace, defense, automotive, networking, and industrial automation. wolfSSL’s […]

Expanding Cross-Compilation Capabilities in Visual Studio With the recent release of wolfSSL, we have significantly improved the cross-compiling capabilities of wolfSSL in Visual Studio, particularly when targeting non-Windows operating systems from a Windows-based development environment. This improvement was introduced in PR #7884 and provides a new build option that makes cross-compilation smoother and more efficient. […]

The team at wolfSSL has taken the core functionality of the wolfSSL embedded SSL/TLS library to the next level and implemented changes to conform to the Required and Mandatory rules from the MISRA-C guidelines. Currently a subset of the wolfCrypt modules are already covered for compliance, including detailed deviation documents (sha256.c, aes.c (CBC/GCM), rsa.c, random.c, […]

wolfSSL is continuously improving its support for DTLS (Datagram Transport Layer Security) to make it easier for developers to handle connection IDs and implement stateless DTLS services. In this blog post, we’ll explore the new APIs introduced in wolfSSL 5.7.6 that simplify these tasks. DTLS is a variant of TLS designed for datagram-based transports like […]

The wolfSSL team is announcing the deprecation of the ARC4 cipher. This decision is part of our ongoing effort to simplify the wolfSSL codebase and focus on supporting the most secure and widely-used ciphers. The ARC4 cipher has been shown to have significant weaknesses, including: Key biases and correlations Plaintext recovery attacks Increased risk of […]

In today’s digital landscape, the need for robust authentication mechanisms has never been more crucial. Among the various methods available, SPAKE (Simple Password-Authenticated Key Exchange) stands out as an enhanced security solution for authenticating users. SPAKE represents a significant advancement over traditional password-based authentication, which often relies on static hashes. By leveraging a shared secret […]

Ladies and gentlemen, it’s story time!! Once upon a time, there was a network administrator that only wanted to use the strongest NIST-approved ECC encryption available within the TLS 1.3 protocol. They picked ECDHE over the secp521r1 curve. When they went to code their application, they wanted the best TLS library available so they naturally […]

As part of our ongoing effort to maintain the highest level of security and performance, we are announcing the upcoming deprecation of RC2 from wolfCrypt. All of our products depend on wolfCrypt for their algorithm implementations so this could have consequences across our whole product line. What is RC2? RC2 is a symmetric-key block cipher […]
