python-crypto - programming error

Published: 5/17/2022Modified: 3/9/2026

Description

PyCrypto before 2.6 does not produce appropriate prime numbers when using an ElGamal scheme to generate a key, which reduces the signature space or public key space and makes it easier for attackers to conduct brute force attacks to obtain the private key.
