Embedded World Nuremberg is this month! We’ll be there talking about security, encryption and everything in between. Stop by and say hello! We’ll be giving away plenty of awesome wolfSSL swag and we’d love to hear about your project. One of the platforms we fully support is of course the ubiquitous Espressif ESP32. We have […]

Exciting news in wolfSSL language bindings: we are currently exploring the possibility of adding bindings for the Ada and Spark languages! Ada is a programming language known for its explicitness, strong typing, and abundance of compile-time checks. It is widely used in safety-critical and high-integrity software. Spark, on the other hand, is a smaller subset […]

It’s been a while since wolfSSH had any new algorithms. I think it is time we had more. wolfCrypt supports a few algorithms wolfSSH doesn’t take advantage of. For encryption and message authentication, wolfCrypt has Poly1305 and CHACHA20 available. There is not a published RFC for using “poly-chacha” with the SSH protocol, but OpenSSH has […]

Bet you didn’t know that wolfSSH has its own stand-alone server application for use on POSIX systems, wolfSSHd. It’ll load OpenSSH style configuration files and will look up users on the local system. It also uses wolfSSH’s built in SFTP service. It doesn’t have privilege separation. In 2023 we are planning on adding privilege separation […]

At wolfSSL, we have been developing a TPM stack with customers for many years called wolfTPM, a portable, open-source TPM 2.0 stack with backward API compatibility, designed for embedded use. It is highly portable, and has native support for Linux and Windows. RTOS and bare metal environments can take advantage of a single IO callback […]

Do you have a favorite crypto algorithm? …or maybe just one that is important to you?  Hash Functions: SHA2, SHA-3, RIPEMD-160, Poly1305, Blake2b, Blake2s, SipHash Block, Stream, and Authenticated Ciphers: AES (CBC, CTR, OFB, XTS, GCM, CCM, GMAC, CMAC), Camellia, ChaCha20 and XChaCha20 Public Key Algorithms: DH, ECDH, ECDSA, RSA, ed448, ed25519, X448, X25519 Could […]

We are establishing a timeline to deprecate our legacy math backend, which is called “normal” or “heap” math.  It will be removed  from the wolfSSL/wolfCrypt library by the end of this year. Currently, our library includes three different math backends that can be used to support public cryptography: Normal math (integer.c) which can be enabled […]

wolfSSL is currently the leader in embedded FIPS certificates. With current FIPS 140-2 certificate #3389 for the wolfCrypt Cryptographic Module, wolfSSL is thrilled to be the first in upcoming FIPS 140-3 certification. Join the wolfSSL team as we cover all things FIPS 140-3. There will be a live Q&A so bring all your FIPS-related questions. […]

Please join the wolfSSL team at WEST 2023 at booth 2849 in San Diego, CA, February 14 – 16 2023. wolfSSL CEO Larry Stefonic, Business Directors Tim Pickering, and Steve Siderewicz, and Sr. Engineer Eric Blankenhorn will be in attendance and as always, we’d love to meet with you. Let’s arrange a time to talk […]

Last year, we were thrilled to announce our support for DTLSv1.3 – we are the first to have a working implementation. 2023 promises to be just as exciting for DTLSv1.3 as 2022 as we already have a number of features planned for the coming months. One of the things we are focusing on is better […]
