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 0.14.1 (06 Nov 2019)

Remove the obsolete six.py file from wheel

  • Release 0.14 (06 Nov 2019)

Bug fixes:
Strict checking of DER requirements when parsing SEQUENCE, INTEGER,
OBJECT IDENTIFIER and BITSTRING objects.
DER parsers now consistently raise UnexpectedDER exception on malformed DER
encoded byte strings.
Make sure that both malformed and invalid signatures raise BadSignatureError.
Ensure that all SigningKey and VerifyingKey methods that should accept
bytes-like objects actually do accept them (also avoid copying input strings).
Make SigningKey.sign_digest_deterministic use default object hashfunc when
none was provided.
encode_integer now works for large integers.
Make encode_oid and remove_object correctly handle OBJECT IDENTIFIERs
with large second subidentifier and padding in encoded subidentifiers.

New features:
Deterministic signature methods now accept extra_entropy parameter to further
randomise the selection of k (the nonce) for signature, as specified in
RFC6979.
Recovery of public key from signature is now supported.
Support for SEC1/X9.62 formatted keys, all three encodings are supported:
"uncompressed", "compressed" and "hybrid". Both string, and PEM/DER will
automatically accept them, if the size of the key matches the curve.
Benchmarking application now provides performance numbers that are easier to
compare against OpenSSL.
Support for all Brainpool curves (non-twisted).

New API:
CurveFp: __str__ is now supported.
SigningKey.sign_deterministic, SigningKey.sign_digest_deterministic and
generate_k: extra_entropy parameter was added
Signature.recover_public_keys was added
VerifyingKey.from_public_key_recovery and
VerifyingKey.from_public_key_recovery_with_digest were added
VerifyingKey.to_string: encoding parameter was added
VerifyingKey.to_der and SigningKey.to_der: point_encoding parameter was
added.
encode_bitstring: unused parameter was added
remove_bitstring: expect_unused parameter was added
SECP256k1 is now part of curves * import
Curves: __repr__ is now supported
VerifyingKey: __repr__ is now supported

Deprecations:
Python 2.5 is not supported any more - dead code removal.
