- This is an easy-to-use implementation of ECDSA
cryptography (Elliptic Curve Digital Signature
Algorithm), implemented purely in Python, released
under the MIT license. 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.(CVE-2019-14859)
