As part of our ongoing effort to maintain the highest level of security and performance, we are announcing the upcoming deprecation of RC2 from wolfCrypt. All of our products depend on wolfCrypt for their algorithm implementations so this could have consequences across our whole product line. What is RC2? RC2 is a symmetric-key block cipher […]

TLS vs. SSH: When To Use Which
TLS and SSH are both widely used protocols used for creating secure connections between two systems over a secure network. But, they are designed for different use cases, so today we are going to take a quick dive into when you should use which. About TLS TLS (Transport Layer Security) is what is most commonly […]

“Hey wolfSSL, care to show us Europeans some post-quantum love?” Of course! Here at wolfSSL we were founded in the USA and most of our team is American. Naturally, we have been following NIST (National Institute of Standards and Technology) standards. That said, we love and cherish our European customers and community as well. Cryptography […]
Read MoreMore TagA slice of security for the Raspberry Pi Pico
Pretty much everyone knows what a Raspberry Pi board is, a very budget-friendly ARM board which runs Linux. What you might not know is that Raspberry Pi also created a very small, cheap, embedded ARM microcontroller range and development board as well. The board is known as the Raspberry Pi Pico and the chip is […]

Read MoreMore TagExtended Key Update for Transport Layer Security (TLS) 1.3
The Extended Key Update extension for (D)TLS 1.3 is a draft proposal for a new key update mechanism. (D)TLS 1.3 lacks perfect forward secrecy (PFS) for long-lived sessions, leaving them vulnerable to key exfiltration attacks. The proposed Extended Key Update mechanism addresses this by incorporating minimal key exchanges during key updates. This safeguards connections by […]

wolfSSL release 5.7.4 includes an exciting new feature. We have implemented Connection ID (CID) support for DTLS 1.2 (RFC 9146). CID is a new feature in DTLS 1.2 that allows for better handling of connection migration. Without it, DTLS connections are tied to the IP 5-tuple making it unable to recover the connection if one […]
