Kudelski Security’s JP Aumasson and X41 D-Sec‘s Markus Vervier were hired to audit Wire‘s cryptography core, the Proteus library. Wire is an application for mobile and desktop

This is probably how a quantum computer looks    ¯\(°_o)/¯ Several readers of the post Defeating Quantum Algorithms with Hash Functions found it difficult to follow without background

This posts describes how to forge public-key signatures computed using mbedTLS’s implementation of RSA-PSS (the RSA-based standard signature scheme). Forging a signature means determining a

In this post I’ll explain why quantum computers are useless to find hash function collisions, and how we can leverage this powerlessness to build post-quantum signature
