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: […]

wolfSSL supports IoT SAFE
The wolfSSL embedded SSL/TLS library supports many popular hardware secure elements from several suppliers using different technologies. Some of these hardware elements are specifically designed to enable end-to-end security in IoT devices, by providing a hardware ‘Root of Trust’, and by providing asynchronous cryptography functionality and key vaults. GSMA is an alliance representing mobile operators, […]
Read MoreMore TagwolfSSL in ExpressVPN’s Lightway
ExpressVPN’s Lightway protocol is out of beta and leverages wolfSSL for secure crypto. As such, the “modern VPN” inherits speed, performance, best-tested security and is able to maintain it’s lightweight mobility. “In terms of the encryption, [ExpressVPN’s Chief Architect, Pete] Membrey explained that Lightway uses wolfSSL. ‘To be clear, we didn’t roll any of our […]

A stream cipher encrypts plaintext messages by applying an encryption algorithm with a pseudorandom cipher digit stream (keystream). Each bit of the message is encrypted one by one with the corresponding keystream digit. Stream ciphers are typically used in cases where speed and simplicity are both requirements. If a 128 bit block cipher (such as […]

Microsoft’s IoT Developer Advocate, Dave Glover, has put together an Azure Sphere Cloud example that uses the wolfMQTT client library and wolfSSL’s Embedded TLS library to demonstrate a secure IoT device connection using the Altair 8800 emulation project. Find the project here and read more about Dave’s effort to get the Altair emulation connected to the […]

At wolfSSL, we pride ourselves on offering the Best-Tested SSL/TLS library on the market. We’re able to do so by conducting regular, diligent, and well-planned testing to maintain a robust and secure library. wolfSSL knows that it is impossible to test every single possible path through the software, but opts to practice an approach that […]
Read MoreMore TagwolfSSL and the ALPACA TLS cross-protocol attack
The ALPACA attack may affect TLS servers who share multiple services and protocols on the same TLS endpoint/instance. The attack is difficult to implement because it requires a Man-in-the-Middle (MitM) position that can intercept and divert the victim’s traffic at the TCP/IP layer. As the TLS protocol does not protect the integrity of the TCP […]

Clavister, one of Europe’s leading cybersecurity vendors, announced that their latest release of OneConnect for macOS, iOS and iPadOS utilizes acceleration from wolfSSL for better performance metrics. “We managed to leverage the acceleration in wolfSSL and could see a reduction of cpu usage (which should translate into better battery life),” says Clavister. If you’re not […]
