Do you want to start using wolfSSL’s DTLS 1.3 implementation?   Want to go even further?  A great reason to start using our DTLS 1.3 stack is that it also supports post-quantum KEMs, Hybrid KEMs and post-quantum signature schemes.  When it comes time to move to post-quantum standards, support for them will likely come in […]

In cryptography when we talk about hardening a library, we mean enabling resistance to timing attacks and cache attacks, using RSA blinding and protecting against glitching. Enabling and Disabling Our code has many related macros which can be controlled via configure script flags such as the harden flag and maxstrength flag. When hardening is enabled, […]

wolfSSL is pleased to announce initial run-time testing of wolfCrypt + NuttX was successfully completed (Crypto algorithm tests and benchmarking) on both BL602 (RISC-V) and NUCLEO-L552ZE-Q (Cortex-M33) targets! wolfSSL engineers are now working on making a publically available drop-in for the NuttX-apps directory that users can take for a spin! The wolfSSL team is very […]

Happy New Year! As we kick off 2023, wolfSSL is excited to announce a series of webinars to help you get started with our software. First up is our webinar on January 5th at 10 AM (PST) on getting started with the wolfSSL TLS library. This webinar will cover a range of topics including an […]

Heard of NuttX?  Fresh out of the Apache incubator, it’s a small RTOS with a focus on POSIX and ANSI standards compliance, scales from 8 to 64-bit microcontrollers, is extensively documented, ported to many platforms, and is very easy to get started with!  Here at wolfSSL we are hard at work testing wolfSSL with NuttX.  […]

wolfSSL are proud to announce a new incremental update to wolfSSH: v1.4.12! In this release, we have wolfSSHD running. It seamlessly fits in where other SSHDs are, and is able to parse and make use of existing sshd_config files that are in place. We are also proud to announce that wolfSSH builds and runs in […]

Merry Christmas! The Christmas release of wolfSSL is here, version 5.5.4! This includes some minor feature additions, QUIC related changes for HAProxy use, port to the MAXQ hardware, improvements in performance, as well as additional enhancements and fixes. In this development cycle we also did testing of using wolfSSL with NuttX, and wolfSSL is ready […]

HPKE (Hybrid Public Key Encryption) is a key encapsulation and encryption standard that allows two parties to derive a common secret and encrypt/decrypt messages using that common secret (https://www.ietf.org/archive/id/draft-irtf-cfrg-hpke-12.txt)  HPKE has three steps in single-shot mode:  Key encapsulation (KEM) – ECC P256, P384, P521 or X25519 Hash based Key Derivation (HKDF) – SHA2-256, SHA2-384, SHA2-512 […]

ECH (Encrypted Client Hello) is a draft extension for TLS 1.3 that enables a client to encrypt its client_hello in the TLS handshake to prevent leaking sensitive metadata that is sent in the clear during the normal TLS handshake. ECH was originally proposed as ESNI (Encrypted Server Name Indication), since the server name indication is […]

In our never-ending quest to have wolfSSL supported and running on all platforms, everywhere, for everyone, we are proud to announce we are now supporting Softcore RISC-V Environments. What is a Softcore RISC-V CPU? We’re glad you asked! Softcore means the electronics are created on a “soft” and reusable FPGA instead of the one-time, hard […]
