  • Factoring RSA Keys with Many Zeros

    Factoring RSA Keys with Many Zeros Interesting research on a new class of weak RSA keys: keys with lots of zeros. It turns out that these keys are out in the wild. The badkeys project is an open-source service that checks public keys for known vulnerabilities. While developing this tool, Hanno collected a massive number…
