Bump ecdsa from 0.11 to 0.13.3

[dependabot]

Bumps ecdsa from 0.11 to 0.13.3.

Release notes

Sourced from ecdsa's releases.

ecdsa 0.13.3

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.

ecdsa 0.13

Fix the argument order for Curve constructor (put openssl_name= at the end,
with a default value) to unbreak compatibility with external callers who used
the 0.11 convention.

ecdsa 0.12

Switch to Versioneer for version-string management (fixing the broken ecdsa.__version__ attribute). Add Curve.openssl_name property. Mention secp256k1 in README, test against OpenSSL. Produce "wheel" distributions. Add py3.4 and pypy3 compatibility testing. Other minor fixes.

Changelog

Sourced from ecdsa's changelog.

• 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)

New API:

• Keys that use explicit curve parameters can now be read and written. Reading of explicit curves can be disabled by using the valid_curve_encodings keyword argument in VerifyingKey.from_pem(), VerifyingKey.from_der(), SigningKey.from_pem(), and SigningKey.from_der().
• Keys can now be written with use of explicit curve parameters, use curve_parameters_encoding keyword argument of VerifyingKey.to_pem(), VerifyingKey.to_der(), SigningKey.to_pem(), or SigningKey.to_der()to specify the format. By defaultnamed_curvewill be used, unless the curve doesn't have an associated OID (as will be the case for an unsupported curve), thenexplicit` encoding will be used.
• Allow specifying acceptable point formats when loading public keys (this also fixes a minor bug where python-ecdsa would accept raw encoding for points in PKCS#8 files). Set of accepted encodings is controlled by valid_encodings keyword argument in ECDH.load_received_public_key_bytes(), VerifyingKey.from_string(), VerifyingKey.from_pem(), VerifyingKey.from_der()`.
• PointJacobi and Point now inherit from AbstractPoint that implements the methods for parsing points. That added from_bytes() and to_bytes() methods to both of them.
• Curve parameters can now be read and written to PEM and DER files. The Curve class supports new to_der(), from_der(), to_pem(), and from_pem() methods.
