wolfSSL is excited to announce we are adding support for the LMS and HSS post-quantum stateful hash-based signature schemes to our wolfCrypt embedded crypto engine. This will be achieved by experimental integration with the hash-sigs LMS/HSS library, similar to our previous libOQS integration. Leighton-Micali Signatures (LMS), and its multi-tree variant, the Hierarchical Signature System (HSS), […]

wolfSSL has tested and provides support for a range of public key cryptographic algorithms on the Microchip Trust Anchor (TA100) – Automotive Grade security IC. This includes RSA with 2048-bit key size as well as ECC with 256 key size, supporting both NIST Prime and Brainpool curves. It’s worth noting that the TA100 is a […]

cURL is an open-source project that provides the command line tool, curl, for transferring data between client and server with URLs, powered by cURL’s library, libcurl. curl and libcurl both provide support for building SSL/TLS libraries, including wolfSSL! Additionally, there is also the tinycurl library which is currently in its beta version. tinycurl also has […]

wolfSSH can make use of X.509 certificates when verifying the peer! Both on the client side and on the server side. The implementation follows RFC 6187 and adds x509v3-ecdsa-sha2-* and x509v3-ssh-rsa to the key exchange algorithms. Instead of the public key, the whole certificate is passed along during authentication and then verified by the peer […]

Looking to add SSL/TLS to your Keil project? The wolfSSL embedded SSL/TLS library is a lightweight SSL/TLS library written in ANSI C and targeted for embedded, RTOS, and resource-constrained environments – primarily because of its small size, speed, and feature set. For Keil MDK and uVision users we provide a CMSIS pack that enables them […]

wolfSSL has significant improvements on how we parse and encode ASN.1 data like certificates and keys. Parsing X.509 certificates, and RSA and ECC keys is important to do correctly. In fact, vulnerabilities come from not checking the validity of the encoding correctly! Reading outside the encoded data can result in crashing of your application or […]

The size of software builds can often be a concern for developers, particularly in embedded systems or other resource-constrained environments. Recently, a change was made to the wolfSSL library that has resulted in smaller build sizes when used with the popular cURL library.  The change in question was made in a pull request to the […]

The CAN bus is becoming ubiquitous in vehicle and factory automation the world over. The devices it connects are becoming more powerful and more connected to the outside world. As such security for the devices on this bus is becoming more and more important. In a previous post we mentioned that we have provided an […]
