* Added support for the Counter Mode KDF defined in SP 800-108
Rev 1.
* Reduce the minimum tag length for the EAX cipher to 2 bytes.
* An RSA object has 4 new properties for the CRT coefficients:
``dp``, ``dq``, ``invq`` and ``invq`` (``invp`` is the same
value as the existing ``u``).
* GH#526: improved typing for ``RSA.construct``.
* GH#534: reduced memory consumption when using a large number
of cipher objects.
* GH#598: fixed missing error handling for
``Util.number.inverse``.
* GH#629: improved typing for ``AES.new`` and the various
mode-specific types it returns. Thanks to Greg Werbin.
* GH#653: added workaround for an alleged GCC compiler bug
that affected Ed25519 code compiled for AVX2.
* GH#658: attribute ``curve`` of an ECC key was not always
the preferred curve name, as it used to be in v3.15.0
(independently of the curve name specified when generating
the key).
* GH#637: fixed typing for legacy modules ``PKCS1_v1_5`` and
``PKCS1_PSS``, as their ``verify()`` returned a boolean.
* GH#664: with OCB mode, nonces of maximum length (15 bytes)
were actually used as 14 bytes nonces.
After this fix, data that was encrypted in past using the
(default) nonce length of 15 bytes can still be decrypted
by reducing the nonce to its first 14 bytes.
* GH#705: improved typing for ``nonce``, ``iv``, and ``IV``
parameters of cipher objects.

* Add support for curve NIST P-224.
* GH#590: Fixed typing info for ``Crypto.PublicKey.ECC``.
* Relaxed ECDSA requirements for FIPS 186 signatures and accept any SHA-2 or
* SHA-3 hash. ``sign()`` and ``verify()`` will be performed even if the hash is stronger
than the ECC key.
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python/python-pycryptodome?expand=0&rev=45
* ECC keys in the SEC1 format can be exported and imported.

* GH#512: Especially for very small bit sizes, ``Crypto.Util.number.getPrime()`` was
occasionally generating primes larger than given the bit size.
* GH#552: Correct typing annotations for ``PKCS115_Cipher.decrypt()``.
* GH#555: ``decrypt()`` method of a PKCS#1v1.5 cipher returned a ``bytearray`` instead of ``bytes``.
* GH#557: External DSA domain parameters were accepted even when the modulus (``p``) was not prime.
This affected ``Crypto.PublicKey.DSA.generate()`` and ``Crypto.PublicKey.DSA.construct()``.
* Added cSHAKE128 and cSHAKE256 (of SHA-3 family).
* GH#558: The flag RTLD_DEEPBIND passed to ``dlopen()`` is not well supported by
`address sanitizers <https://github.com/google/sanitizers/issues/611>`_.
It is now possible to set the environment variable ``PYCRYPTDOME_DISABLE_DEEPBIND``
to drop that flag and allow security testing.

* Fixed a potential memory leak when initializing block ciphers.
* GH#466: ``Crypto.Math.miller_rabin_test()`` was still using the system random
source and not the one provided as parameter.
* GH#469: RSA objects have the method ``public_key()`` like ECC objects.
The old method ``publickey()`` is still available for backward compatibility.
* GH#476: ``Crypto.Util.Padding.unpad()`` was raising an incorrect exception
in case of zero-length inputs. Thanks to Captainowie.
* GH#491: better exception message when ``Counter.new()`` is called with an integer
``initial_value`` than doesn't fit into ``nbits`` bits.
* GH#496: added missing ``block_size`` member for ECB cipher objects. Thanks to willem.
* GH#500: ``nonce`` member of an XChaCha20 cipher object was not matching the original nonce.
