wolfSSL is excited to announce support for Espressif ESP32 hardware acceleration to the wolfSSL embedded SSL/TLS library! The ESP32-WROOM-32 is a powerful, generic Wi-Fi+BLE MCU module with high flexibility, and is easily interactable with the wolfSSL embedded SSL/TLS library. As wolfSSL is highly portable and the ESP32-WROOM-32 is highly flexible, if your application has any […]

wolfSSL embedded SSL/TLS support the latest Microchip ATECC508A and ATECC608A I2C cryptographic coprocessors. Not only is wolfSSL compatible with CryptoAuthLib, wolfSSL has also been tested on both the 508A and the 608A. Prerequisites: Requires the Microchip CryptoAuthLib (https://github.com/MicrochipTech/cryptoauthlib.git) Examples: wolfSSL uses PK (Public Key) callbacks for the TLS crypto operations wolfCrypt uses the WOLFSSL_ATECC508A macro […]

Recently, the National Institute of Standards and Technology (NIST) completed the validation of the wolfCrypt module version 4 for an updated Federal Information and Processing Standards (FIPS) 140-2 certificate. This new certificate includes updated and more secure algorithms added to the wolfCrypt module’s boundary, some of which are listed below. FIPS 140-2 is a government […]

wolfSSL can now be used to replace OpenSSL in Secure Socket Funneling (SSF)! Secure Socket Funneling (SSF) is a network tool and toolkit. It provides simple and efficient ways to forward data from multiple sockets (TCP or UDP) through a single secure TLS tunnel to a remote computer. Features: Local and remote TCP port forwarding […]

wolfSSL’s wolfSSH lightweight SSH library shares some similarities with the wolfSSL library – it has minimal resource usage, high performance, and is highly portable. An example that showcases the portability of wolfSSH is its ability to also be built within multiple operating environments, including Windows CE. Windows CE is an operating system that is a […]

While wolfSSL does provide one of the most secure embedded SSL/TLS libraries a high-powered and lightweight encryption engine, and other products, wolfSSL also provides various services. One of these services is the exemplary support offered by the wolfSSL support team. On average, wolfSSL receives between 700 and 800 support inquiries each year through support@wolfssl.com. These […]

wolfSSL provides many different embedded, lightweight, and portable products. One of which is the wolfSSH lightweight embedded SSH Library, based on the SSHv2 protocol. wolfSSH comes with support for a long list of platforms, multiple hashing functions, SCP, SFTP, and more. Additionally, wolfSSH provides support for remote execution, one of the core features of an […]

wolfTPM version 1.5.0 was recently released, and features many new updates and additions to the wolfTPM library. Summary: Added support for the Microchip ATTPM20 TPM 2.0 module Added Barebox bootloader support. Added TPM wrappers for HMAC, AES Key Loading. Added Benchmarking support for RNG, AES, Hashing and TLS. Improvements for TLS client/server examples and overall […]

wolfSSL provides many different products, one of which is the wolfSSH library. wolfSSH itself provides a lightweight embedded SFTP solution. SFTP can be used to securely transfer files, and to manage the filesystem of a peer. wolfSSH’s implementation of SFTP uses less than a third of the memory that OpenSSH does for a SFTP connection. […]

wolfSSL’s embedded SSL/TLS library has included support for TLS 1.3 since early releases of the TLS 1.3 draft. Since then, wolfSSL has remained up-to-date with the TLS 1.3 specification. In this post, the major upgrades of TLS 1.3 from TLS 1.2 are outlined below: TLS 1.3 This protocol is defined in RFC 8446. TLS 1.3 […]
