Join wolfSSL engineer Eric Blankenhorn to learn more about our wolfMQTT library, built to be multi-platform, space conscious and extensible. The wolfMQTT library is a client implementation of the MQTT written in C for embedded use, and supports SSL/TLS via the wolfSSL library. Bring your questions for the Q&A session to follow! Watch the webinar […]

Here at wolfSSL, we like to be on the cutting edge of things. Sometimes that means supporting algorithms before they are widely adopted which can lead to supporting algorithms that do not get wide adoption. This has been the case for the following algorithms: – Rabbit – HC128 – IDEA – Camellia To reduce code […]

Here at wolfSSL we are at the cutting edge of cryptography and protocols.  For example, even before TLS 1.3 was fully standardized, we were implementing it in line with the draft RFCs. Also, with the progress that is being made in the quantum computing space, we are keeping abreast of post-quantum cryptography and the standardization […]

Happy Holidays! The wolfSSL holiday release is available for download! This release includes more compatibility layer expansions, updates to the version of open source projects supported, post quantum additions, and new hardware port additions to name some of what was included. As well as 2 vulnerabilities fixed in the release bundle.  A major performance upgrade […]

This webinar will provide attendees with the basics and best practices needed to get started using the wolfSSL TLS library in products and projects into 2022. Topics will include a brief overview of TLS 1.3, wolfSSL package structure, how to build wolfSSL, running the wolfCrypt cryptography test and benchmark applications, wolfSSL basic API usage, tips […]

We’re pleased to announce that we’ve added support for SNI and TLSx options for CMake builds in wolfSSL v5.0.0! Server Name Indication (SNI) is useful when a server hosts multiple “virtual” servers at a single underlying network address. It may be desirable for clients to provide the name of the server which it is contacting.  […]

WolfSSL v5.0.0 includes an added build option to configure wolfSSL with the alternate certificate chain feature enabled! Default wolfSSL behavior is to require validation of all presented peer certificates. This also allows loading intermediate Certificate Authorities (CA’s) as trusted and ignoring no signer failures for CA’s up the chain to root. Enabling alternate certificate chain […]

WolfSSL v5.0.0 includes an added build option for use with our portable command-line utility product, wolfCLU! wolfCLU (Command Line Utility) is backed by the best-tested crypto using wolfCrypt and it can make use of FIPS builds with wolfSSL. You can download wolfCLU on Github today for use with the wolfSSL embedded SSL/TLS library! This added […]

We are excited to announce wolfSSL’s support for the NXP SE050. The wolfSSL SE050 port supports a variety of algorithms including: SHA, SHA2-224, SHA2-256, SHA2-384, SHA2-512, AES-CBC, AES-ECB, ECDSA, ECDHE and most notably ED25519 / CURVE25519. In the tested configuration a Raspberry Pi 2b was connected to the SE050 dev kit through a header board. […]

lwIP (lightweight IP) is as the name suggests, a lightweight Open Source networking stack that is used in a lot of embedded systems. wolfSentry is a relatively new product by wolfSSL that provides a lightweight IDPS (Intrusion Detection and Prevention System). Of course, together the two should pair quite nicely, so the team at wolfSSL […]
