In early March 2018 we added support for the new Microsoft Azure Sphere microcontroller, which uses Pluton security for ECC P-256 key generation and sign/shared secret (ECDSA/ECDHE). This micro is targeting the embedded IoT space and supports Azure IoT cloud or any of your choosing. This chip uses wolfSSL and wolfCrypt for solving its TLS […]

We have added ST33TP support for the I2C and SPI version of the TPM 2.0 modules to the wolfTPM library. STMicroelectronics ST33TP* TPM 2.0 Module Specifications: Interfaces: SPI (33MHz) or I2C (400kHz) Algorithms: RSA (1024/2048), ECC (224/256), AES (128/192/256), SHA1, SHA2, HMAC Certifications: CC EAL4+ and FIPS 140-2 Level 2 NV Storage: 112KB wolfTPM Library […]

The wolfSSL (formerly CyaSSL) embedded SSL library supports lwIP, the light weight internet protocol implementation, out of the box.  The user merely needs to define WOLFSSL_LWIP or uncomment the line /* #define WOLFSSL_LWIP */ in os_settings.h to use wolfSSL with lwIP.   The focus of lwIP is to reduce RAM usage while still providing a […]

wolfSSL supports the STMicroelectronics STSAFE-A100 I2C cryptographic coprocessor. It’s capable of ECC sign/verify (ECDSA) and shared secret (ECDH) operations for 256-bit and 384-bit (NIST Prime and Brainpool) curves. It has 2 key slots and 6KB of non-volatile memory for certificate or data storage.  Prerequisites: Requires the STSAFE-A Device Library from ST Requires wolfSSL interface and […]

wolfSSL embedded SSL/TLS support the latest Microchip ATECC508A and ATECC608A I2C cryptographic coprocessors. The latest round of fixes to support the most recent CryptoAuthLib are in a pull request here (https://github.com/wolfSSL/wolfssl/pull/1815). We have not yet tested with the ATECC608A due to lack of hardware, but wolfSSL is compatible with the latest CryptoAuthLib. We plan on […]

Have you heard talk about SSL 3.0, TLS 1.0, TLS 1.1, TLS 1.2, and TLS 1.3 but never really knew the differences between the different versions? Secure Socket Layer (SSL) and Transport Security Layer (TLS) are both cryptographic protocols which provide secure communication over networks. These different versions are all in widespread use today in […]

Apache Mynewt is a operating system which is Open Source, modular and realtime (RTOS). It is designed for IoT devices that have limited memory and storage and need to run for a long time with minimal power consumption. More details of Apache Mynewt can be found on the project’s website: http://mynewt.apache.org/ wolfSSL is happy to […]

wolfSSL now supports Xilinx SoCs and FPGAs. The wolfSSL embedded SSL/TLS library can be used with FPGAs which use the MicroBlaze CPU and/or Zynq and Zynq UltraScale+ SoCs. Improved performance speeds with using the hardware crpyto can be seen. Increasing AES-GCM, RSA, and SHA3 operations performance. In addition to the performance gained a user also […]

We have had some reports of low-end embedded systems taking 10-20 seconds to establish a TLS connection when generating a shared secret using the ECDH algorithm. We wanted to remind our users of the fixed-point caching mechanism provided by wolfSSL. Users can enable fixed point caching with the configure option –enable-fpecc or by defining FP_ECC […]
