Are you looking for an excellent Windows SSHd service? wolfSSL is adding Windows support for our SSHd implementation! This allows for running wolfSSHd as a service in Windows 10 and newer environments, handling SFTP, SCP and shell connections.  If you have any questions or run into any issues, contact us at facts@wolfssl.com, or call us […]

On i.MX8 devices there is a SECO (https://www.nxp.com/docs/en/application-note/AN12906.pdf) hardware module available for heightened security. This module handles AES operations, limited ECC operations, key storage, and provides a RNG. wolfSSL has long since been expanded to make use of the SECO where possible. A full step by step guide for building wolfSSL and setting up Linux […]

wolfBoot is now ported and available for intel Tiger Lake systems! wolfBoot leverages wolfCrypt DO-178 for its cryptographic functionality. The initial operating system targeted for boot is Green Hills Integrity, but we expect to add support for DDCI’s DEOS, SYSGO, Wind River’s VxWorks, and LynxOS over time. Currently, wolfCrypt is in service or “in the […]

A quite unique feature of wolfBoot is the possibility to update the firmware using signed incremental updates. The mechanism relies on a delta algorithm that produces a small update package. Instead of transferring the entire binary image of the firmware update, incremental updates only contain the binary difference with the previous version. Distributing a new […]

A block cipher is an encryption method that applies a deterministic algorithm along with a symmetric key to encrypt a block of text, rather than encrypting one bit at a time as in stream ciphers. For example, a common block cipher, AES (Advanced Encryption Standard), encrypts 128 bit blocks with a key of predetermined length: […]

IoT-SAFE, IoT SIM Applet For Secure End-to-End Communication, is a standard mechanism, based on the use of SIM cards (both physical SIM and ESIM) as Root-of-Trust to secure applications and services running on embedded systems connected through the mobile network. IoT-SAFE is standardized and promoted by GSMA, and is currently being implemented in the mobile market […]

With the release of wolfTPM, it may be useful to understand the differences and benefits of TPM 1.2 and TPM 2.0. The table below outlines some of the differences/similarities between TPM 1.2 and TPM 2.0 in a side-by-side comparison. TPM 1.2 TPM 2.0 One-size-fits-all specification consists of three parts Required algorithms: RSA-1024, RSA-2048; SHA-1 (hashing […]

Watch the webinar here: Intro and update of wolfSentry wolfSSL engineer, Daniel Douzzer, will showcase how […]

Are you a thought leader in the world of embedded devices? If so, you will need to make yourself aware of the coming impacts of post-quantum cryptography and how it will affect the various industries and verticals that you participate in. Have a listen to Entrust’s Cybersecurity Institute’s second episode of the their post-quantum podcast […]

We are excited to tell you about our partner collaboration with ST Micro! This collaboration is a video series about wolfBoot, a secure bootloader and the STM32, a family of 32-bit microcontrollers. This is a 4 part video series showing how to use wolfBoot on various STM32 microcontrollers. Video 1: wolfBoot for STM32, Part 1: […]
