Changelog

Sourced from ecdsa's changelog.

• Release 0.18.0 (09 Jul 2022)

New API:

• 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.

• Release 0.17.0 (27 May 2021)
