Mon Oct 24 17:14:10 UTC 2022 - Ben Greiner <code@bnavigator.de>

- Update to 0.18.0
  * New features:
    + Support for EdDSA (Ed25519, Ed448) signature creation and
      verification.
    + Support for Ed25519 and Ed448 in PKCS#8 and public key files.
    + Support for point precomputation for EdDSA.
  * 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.
    + curve_by_name in curves module to get a Curve object by
      providing curve name.
  * 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.
    + 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.
- Also remove the conditional definition of python_module.

Tue Aug 31 10:18:41 UTC 2021 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>

- Update to 0.17.0
  * 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 default `named_curve` will be used, unless the
    curve doesn't have an associated OID (as will be the case for an unsupported
    curve), then `explicit` 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.
  * Describe in detail which methods can raise `RSZeroError`, and that
    `SigningKey.sign_deterministic()` won't raise it.
  * Correctly truncate hash values larger than the curve order (only impacted
    custom curves and the curves added in this release).
  * Correctly handle curves for which the order is larger than the prime
    (only impacted custom curves and the secp160r1 curve added in this release).
  * Fix the handling of `==` and `!=` for `Public_key`, `Private_key`, `Point`,
    `PointJacobi`, `VerifyingKey`, and `SigningKey` so that it behaves
    consistently and in the expected way both in Python 2 and Python 3.
  * Implement lock-less algorithm inside PointJacobi for keeping shared state
    so that when a calculation is aborted with KeyboardInterrupt, the state
    doesn't become corrupted (this fixes the occasional breakage of ecdsa in
    interactive shells).
  * The `speed.py` script now provides performance for signature verification
    without the use of precomputation.
  * New curves supported: secp112r1, secp112r2, secp128r1, secp160r1.
  * Use 2-ary Non-Adjacent Form for the combined multiply-add. This speeds up
    single-shot verify (i.e. without precomputation) by about 4 to 5%.
  * Use native Python 3.8 support for calculating multiplicative inverses.
  * Include Python 3.9 in PyPI keywords.
  * More realistic branch coverage counting (ignore Python version-specific
    branches).
  * Additional test coverage to many parts of the library.
  * Migrate to Github Actions for Continuous Testing.

Sun Dec 20 09:21:59 UTC 2020 - Dirk Müller <dmueller@suse.com>

- update to to 0.16.1:
  * `VerifyingKey.precompute()` supports `lazy` argument to delay
  precomputation to the first time the key is used to verify a signature.
  * 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 
  * Speed up library load time by calculating the generator point multiplication
  tables the first time the points are used, not when they are initialised.

-------------------------------------------------------------------
Thu Sep 17 11:14:57 UTC 2020 - Dirk Mueller <dmueller@suse.com>

- update to 0.16.0:
  * Support for reading and writing private keys in PKCS#8 format.
  * `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).
  * Correctly calculate signatures for private keys equal to n-1.
  * Make `PointJacobi` and thus `SigningKey` and `VerifyingKey` pickleable.

  `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.
