RECENT BLOG NEWS

Recent releases of wolfSSL have included new assembly code targeted at the Intel x86_64 platform. Large performance gains have been made and are being discussed over six blog posts of which this is part 3. In this blog, we will talk about the performance of SHA-256 and SHA-512. The most commonly used digest algorithms are […]

Recent releases of wolfSSL have included new assembly code targeted at the Intel x86_64 platform. Large performance gains have been made and are being discussed over six blog posts of which this is part 2. In this blog, we will talk about the performance of ChaCha20-Poly1305. ChaCha20-Poly1305 is a relatively new authenticated encryption algorithm. It […]

Recent releases of wolfSSL have included new assembly code targeted at the Intel x86_64 platform. Large performance gains have been made which are being discussed over a six blog post series. In this first blog, we will talk about the performance of AES-GCM. The assembly code for AES-GCM has been rewritten to take best advantage of the […]

We are excited to announce that wolfCrypt v4.0 is currently in process for CMVP validation for FIPS 140-2! We are adding more algorithms to our security boundary including ECDSA, ECDHE, AES-GCM, AES-CCM, SHA-3, and RSA-PSS. Also included is FIPS 186-4 compliant key generation for both RSA and ECC. We will be able to offer TLSv1.3 with […]

Two modes of AES have been added to the embedded TLS library wolfSSL; AES-CFB and AES-XTS. AES CFB (Cipher FeedBack) mode is a stream cipher mode of AES. For the first 16 bytes it encrypts an IV using AES and xor’s the result with the plain text for encryption or the cipher text for decryption. […]

wolfSSL is pleased to announce we are in the process of adding FIPS + SGX to our FIPS certificate! We have updated our SGX-Linux support and are working on adding an example client and server to the existing SGX-Windows project for a complete solution. If you are working with SGX and need FIPS validated crypto […]

wolfSSL is a growing company looking to add a top notch embedded systems software engineer to our organization. wolfSSL develops, markets and sells the leading Open Source embedded SSL/TLS protocol implementation, wolfSSL. Our users are primarily building devices or applications that need security. Other products include wolfCrypt embedded cryptography engine, wolfMQTT client library, and wolfSSH. […]

We’ve fully added support for SHA-3 to the wolfSSL embedded TLS library. We have also included SHA-3 support to HMAC and HKDF. Our SHA-3 offering includes 224, 256, 384, and 512-bit digests. It is tied into our hashing and signature infrastructure, so it will be available to TLS v1.2 or TLS v1.3 when the IETF […]

At wolfSSL, we are dedicated to 3rd party integration and have been improving our support for Nginx. wolfSSL now has tested patches for Nginx 1.13.8, 1.12.2 and other point releases. Nginx builds with OpenSSL by default and this makes getting FIPS 140-2 compliance difficult. Compiling Nginx with wolfSSL is simple and we can help you […]

We’ve expanded our STM32F series support in the wolfSSL embedded TLS library to include the STM32F1, STM32F2, STM32F4 and STM32F7. This supports using either the CubeMX HAL or the Standard Peripheral Library. If the chip supports symmetric hardware crypto such as AES (CBC/GCM), 3DES, MD5, SHA1 or SHA256 we support using this from wolfCrypt native […]
