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.
|
||
|
|
|
||
|
|
This library provides key generation, signing, and verifying, for five popular
|
||
|
|
NIST "Suite B" GF(p) curves, with key lengths of 192, 224, 256, 384, and 521
|
||
|
|
bits. The "short names" for these curves, as known by the OpenSSL tool, are:
|
||
|
|
prime192v1, secp224r1, prime256v1, secp384r1, and secp521r1. No other curves
|
||
|
|
are included, but it would not be too hard to add more.
