ecdsa
A pure-Python implementation of ECDSA, EdDSA, and ECDH for elliptic curve cryptography.
What is ecdsa?
python-ecdsa is a pure-Python library that implements elliptic curve cryptography, specifically ECDSA for digital signatures, EdDSA for Edwards-curve signatures, and ECDH for key agreement. It solves the need for a portable, dependency-light cryptographic tool for testing, education, and environments where native extensions are impractical.
Developers and researchers needing a pure-Python elliptic curve cryptography library for interoperability testing, educational projects, or environments where C extensions cannot be used.
It offers a straightforward, portable implementation with support for multiple curves and OpenSSL compatibility, without requiring external C libraries, making it uniquely suitable for testing and learning.
