Release notes
*Sourced from [ecdsa's releases](https://github.com/warner/python-ecdsa/releases).*
> ## ecdsa 0.14.1
> Remove the obsolete `six.py` file from wheel distribution file on pypi
>
> ## ecdsa 0.14
> tl;dr:
> -----
> * support for Brainpool curves
> * better test coverage, fixed bugs found by it
> * support for compressed point representation
>
> 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
> ... (truncated)
