Ctf wiener's attack
Web2. Yes, you can use small public exponents (e.g., 3 is fine), as long as you never encrypt the same plaintext under three or more RSA public keys with exponent 3. Otherwise, there is "Hastad's broadcast attack" that can extract the plaintext, without needing to … The Wiener's attack, named after cryptologist Michael J. Wiener, is a type of cryptographic attack against RSA. The attack uses the continued fraction method to expose the private key d when d is small.

Wiener has shown that when the RSA protocol is used with a decrypting exponent, d, which is less than N1=4 and an encrypting exponent, e, approximately the same size as N, then d can usually be found from the continued fraction approximation of e=N.
