Factoring "short-sleeve" RSA keys with polynomials
<p>What happens when the bits of an RSA private key are heavily biased toward 0 instead of being randomly generated? The public key’s bits could be biased enough for us to detect these incorrectly generated keys in the wild. Together with Hanno Böck of the <a href="https://badkeys.info/">badkeys</a> project, we found hundreds of unique keys that not only have this property, but can be quickly fact
