About this tag
Dan Shumow is a Senior Software Development Engineer in Security & Cryptography at Microsoft Research, co-author of a tool to detect SHA-1 hash collisions. On WindowsForum.com, discussions reference his work in the context of the SHAttered research, which demonstrated the first full SHA-1 collision. The tool helps identify collision attacks in files, relevant to digital certificates and code signing security. This tag covers topics around cryptographic research, hash collisions, and Microsoft's role in advancing security measures.

SHA-1 Collisions Research
Today, a group of eight researchers from across the security industry released a research report on SHA-1 that demonstrates for the first time, a “hash collision” for the full SHA-1 hash algorithm (called “SHAttered”). This is a significant step toward understanding this type of security issue...- News
