|
|
Thu Apr 13 22:41:01 UTC 2023 - Matej Cepl <mcepl@suse.com>

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.

|
|
|
|
- update to 0.13 (bsc#962291)
|
|
|
|
Fix the argument order for Curve constructor (put openssl_name= at the end,

|
|
the 0.11 convention.

|
`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.
