Bumps ecdsa from 0.13 to 0.13.3.

Release notes

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.

Changelog

Sourced from ecdsa's changelog.

Release 0.16.1 (12 Nov 2020)

New API: VerifyingKey.precompute() supports lazy argument to delay precomputation to the first time the key is used to verify a signature.

Doc fixes: Documentation for the VerifyingKey.precompute() method.

Bug fix: Make created signatures correct when the hash used is bigger than the curve order bit size and the curve order is not a multiple of 8 (this affects only users of custom curves or hashes with output larger than 512 bits).

Performance: Speed up library load time by calculating the generator point multiplication tables the first time the points are used, not when they are initialised.

Maintenance: Include Python 3.9 in CI testing. Test coverage for the VerifyingKey.precompute() method. Small speed-ups for the test suite.

Release 0.16.0 (27 Aug 2020)

New features: Support for reading and writing private keys in PKCS#8 format.

New API: to_pem and to_der now accept new parameter, format, to specify the format of the encoded files, either the dafault, legacy "ssleay", or the new pkcs8 to use PKCS#8. Note that only unencrypted PKCS#8 files are supported. Add allow_truncate to verify in VerifyingKey, it defaults to True, when specified as False, use of large hashes smaller than curves will be disallowed (as it was in 0.14.1 and earlier).

Bug fix: Correctly calculate signatures for private keys equal to n-1. Make PointJacobi and thus SigningKey and VerifyingKey pickleable.

Doc fixes: to_pem functions return bytes not str, document them as such. from_pem and from_pem in SigningKey returns SigningKey, document them as such.

Maintenance: Ensure that version checks will work with Python 4. Format the source with black. Fix uses of assert_ in test suite.
