Fix CVE-2019-14853 - possible DoS caused by malformed signature decoding
Fix CVE-2019-14859 - signature malleability caused by insufficient checks of DER encoding
Also harden key decoding from string and DER encodings.
ecdsa 0.13.2
Restore compatibility of setup.py with Python 2.6 and 2.7.
ecdsa 0.13.1
Fix the PyPI wheel - the old version included .pyc files.
curve_by_name in curves module to get a Curve object by providing curve
name.
Bug fix:
Make the VerifyingKey encoded with explicit parameters use the same
kind of point encoding for public key and curve generator.
Better handling of malformed curve parameters (as in CVE-2022-0778);
make python-ecdsa raise MalformedPointError instead of AssertionError.
Doc fix:
Publish the documentation on https://ecdsa.readthedocs.io/,
include explanation of basics of handling of ECC data formats and how to use
the library for elliptic curve arithmetic.
Make object names more consistent, make them into hyperlinks on the
readthedocs documentation.
Make security note more explicit (Ian Rodney)
Fix the explicit vs named_curve confusion in VerifyingKey docs.
Maintenance:
Updated black version; slight changes to formatting
Include interoperability tests for Ed25519 and Ed448 with OpenSSL.
Release 0.18.0-beta2 (05 Jan 2022)
New features:
Support for point precomputation for EdDSA.
Maintenance:
Fix few typos (thanks to Tim Gates and Kian Meng Ang).
Bug fix:
Accept private EdDSA keys that include public key in the ASN.1 structure.
Fix incompatibility with Python 3.3 in handling of memoryviews of empty
strings.
Release 0.18.0-beta1 (03 Aug 2021)
New features:
Support for EdDSA (Ed25519, Ed448) signature creation and verification.
Support for Ed25519 and Ed448 in PKCS#8 and public key files.
New API:
CurveEdTw class to represent the Twisted Edwards curve parameters.
PointEdwards class to represent points on Twisted Edwards curve and
provide point arithmetic on it.
