tlsfuzzer/python-ecdsa
This repository implements ECDSA cryptographic signatures, which are fundamentally vulnerable to quantum attacks via Shor's algorithm. The library contains 143 high-severity quantum-vulnerable findings across elliptic curve implementations, plus critical usage of broken hash functions (SHA-1, MD5) that compound the security risks. Immediate migration planning to post-quantum cryptography is essential for any production deployments.
