WebMay 26, 2015 · There's no known algorithm to solve this problem fast in every circumstance, as this would mean you'd be able to break RSA. IMO the best route would be to try the most used e, like 3, 17, 2 16 + 1, then brute-force the first ≈ 2 32 ones and then try to apply Wieners's attack, if l o g 2 ( e) < 160 – SEJPM May 25, 2015 at 16:24 Show 4 more …

WebOne approach to obtaining prime numbers in instantiations of these cryptographic primitives is to produce such numbers as they are needed on whatever device requires them. This is accomplished by sampling random integers and checking for primality. This process can be computationally intensive to the point of being prohibitively so. WebNew to CryptoHack?
