authored by Daniel Stenberg – original post: https://gist.github.com/bagder/5970df691b7cdef65e95d3d48ebd8659 You most probably already know why you would use curl and if I’m right, you’re also a fan of using the right tool for the job. But do you know why others use curl and why they switch from other solutions to relying on curl for their current […]
Read MoreMore TagwolfSSL Apache Port Coming Soon!
wolfSSL provides the wolfSSL embedded SSL/TLS library, which is a fast, secure, and highly portable implementation of the SSL/TLS protocols. As part of being highly portable, the wolfSSL library is frequently being ported to various other software modules and devices for users to easily implement wolfSSL’s features. One of these more recent ports that wolfSSL […]
Read MoreMore TagwolfSSL and the Zombie POODLE and GOLDENDOODLE Attacks
The wolfSSL library is NOT vulnerable to these attacks, thanks to previous fixes we’ve made and our extensive testing. These attacks were presented by Craig Young at BlackHat Asia 3/29/2019 (slides). Both attacks target the MAC and Padding used for TLS v1.2 with AES CBC cipher suites. TLS padding occurs when a record is not […]
