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#500: ``nonce`` member of an XChaCha20 cipher object was not matching the original nonce.
Thanks to Charles Machalow.
Other changes
-------------

- Update to 3.4.12 (5 February 2018)
- Resolved issues
* GH#129. pycryptodomex could only be installed via wheels.
- Update to 3.4.11 (5 February 2018)
- Resolved issues
* GH#121. the record list was still not correct due to PEP3147
and __pycache__ directories. Thanks again to John O'Brien.
- Update to 3.4.10 (2 February 2018)
- Resolved issues
* When creating ElGamal keys, the generator wasn't a square residue:
ElGamal encryption done with those keys cannot be secure under
the DDH assumption. Thanks to Weikeng Chen.
- Update to 3.4.9 (1 February 2018)
- New features
* More meaningful error messages while importing an ECC key.
- Resolved issues
* GH#123 and #125. The SSE2 command line switch was not always passed on
32-bit x86 platforms.
* GH#121. The record list (--record) was not always correctly filled for
the pycryptodomex package. Thanks to John W. O'Brien.
- Update to 3.4.8 (27 January 2018)
- New features
* Added a native extension in pure C for modular exponentiation, optimized
for SSE2 on x86.
In the process, we drop support for the arbitrary arithmetic library MPIR
on Windows, which is painful to compile and deploy.
The custom modular exponentiation is 130% (160%) slower on an Intel CPU
in 32-bit (64-bit) mode, compared to MPIR. Still, that is much faster
that CPython's own `pow()` function which is 900% (855%) slower than MPIR.
Support for the GMP library on Unix remains.
* Added support for *manylinux* wheels.
* Support for Python 3.7.
- Resolved issues
* The DSA parameter 'p' prime was created with 255 bits cleared
(but still with the correct strength).
* GH#106. Not all docs were included in the tar ball.
Thanks to Christopher Hoskin.
* GH#109. ECDSA verification failed for DER encoded signatures.
Thanks to Alastair Houghton.
* Human-friendly messages for padding errors with ECB and CBC.
- provide python-crypto 2.6.1
