ecdsa: ecdsa (ECDSA cryptographic signature library) ecdsa: ecdsa: This is an easy-to-use implementation of ECDSA cryptography ecdsa: (Elliptic Curve Digital Signature Algorithm), implemented purely ecdsa: in Python, released under the MIT license. ecdsa: ecdsa: With this library, you can quickly create keypairs (signing ecdsa: key and verifying key), sign messages, and verify the signatures. ecdsa: ecdsa: Project URL: https://pypi.python.org/pypi/ecdsa/ ecdsa:
