The `ecdsa` PyPI package is a pure Python implementation of ECC (Elliptic Curve Cryptography) with support for ECDSA (Elliptic Curve Digital Signature Algorithm), EdDSA (Edwards-curve Digital Signature Algorithm) and ECDH (Elliptic Curve Diffie-Hellman). Versions 0.18.0 and prior are vulnerable to the Minerva attack. As of time of publication, no known patched version exists.

python-ecdsa has been found to be subject to a Minerva timing attack on the P-256 curve. Using the `ecdsa.SigningKey.sign_digest()` API function and timing signatures an attacker can leak the internal nonce which may allow for private key discovery. Both ECDSA signatures, key generation, and ECDH operations are affected. ECDSA signature verification is unaffected. The python-ecdsa project considers side channel attacks out of scope for the project and there is no planned fix.

El paquete PyPI `ecdsa` es una implementación pura de Python de ECC (criptografía de curva elíptica) con soporte para ECDSA (algoritmo de firma digital de curva elíptica), EdDSA (algoritmo de firma digital de curva Edwards) y ECDH (curva elíptica Diffie-Hellman). Las versiones 0.18.0 y anteriores son vulnerables al ataque Minerva. Al momento de la publicación, no existe ninguna versión parcheada conocida.
