A new possible method of factorization for arbitrary semiprimes? Weil pairing factorization

I was noticing something: unlike on semiprimes, it s quite easy to generate a point of known small order on a curve defined on a semiprime without knowing it s factorization. The idea is to transfer this small order to the underlying semiprime using a pairing method derived from the …

I built a visual tool to explain entropy and randomness in cryptography

After reading about cases where weak entropy led to unsafe keys and people losing funds (recent bitcoin COLDCARD attack) , I decided to learn more about entropy and how it is generated. There are different ways to generate entropy, like TRNGs, PRNGs, rolling dice, or flipping coins. But for me, …
