python3-ecdsa - 0.13-3+deb10u1 main

This is an easy-to-use implementation of ECDSA cryptography (Elliptic Curve
Digital Signature Algorithm), implemented purely in Python. With this library,
you can quickly create keypairs (signing key and verifying key), sign messages,
and verify the signatures. The keys and signatures are very short, making them
easy to handle and incorporate into other protocols.
