2.4
===
* Python 3 support! (Thorsten E. Behrens, Anders Sundman)
PyCrypto now supports every version of Python from 2.1 through 3.2.
* Timing-attack countermeasures in _fastmath: When built against
libgmp version 5 or later, we use mpz_powm_sec instead of mpz_powm.
This should prevent the timing attack described by Geremy Condra at
PyCon 2011:

* New hash modules (for Python >= 2.5 only): SHA224, SHA384, and
SHA512 (Frédéric Bertolus)
* Configuration using GNU autoconf. This should help fix a bunch of
build issues.
* Support using MPIR as an alternative to GMP.
* Improve the test command in setup.py, by allowing tests to be
performed on a single sub-package or module only. (Legrandin)
You can now do something like this:
python setup.py test -m Hash.SHA256 --skip-slow-tests
* Fix double-decref of "counter" when Cipher object initialisation
fails (Ryan Kelly)
* Apply patches from Debian's python-crypto 2.3-3 package (Jan
Dittberner, Sebastian Ramacher):
- fix-RSA-generate-exception.patch
- epydoc-exclude-introspect.patch
- no-usr-local.patch
* Fix launchpad bug #702835: "Import key code is not compatible with
GMP library" (Legrandin)
* More tests, better documentation, various bugfixes.
pkgsrc changes:
- add a patch to fix an hardcoded interpreter path
- add a patch to actually find gmp library.
- add CONFLICTS with py-amkCrypto, both have files in common.
upstream changes:
2.3
===
* Fix NameError when attempting to use deprecated getRandomNumber()
function.
* _slowmath: Compute RSA u parameter when it's not given to
RSA.construct. This makes _slowmath behave the same as _fastmath in
this regard.
* Make RSA.generate raise a more user-friendly exception message when
the user tries to generate a bogus-length key.
2.2
===
* Deprecated Crypto.Util.number.getRandomNumber(), which had confusing
semantics. It's been replaced by getRandomNBitInteger and
getRandomInteger. (Thanks: Lorenz Quack)
* Better isPrime() and getPrime() implementations that do a real
Rabin-Miller probabilistic primality test (not the phony test we did
before with fixed bases). (Thanks: Lorenz Quack)
* getStrongPrime() implementation for generating RSA primes.
(Thanks: Lorenz Quack)
* Support for importing and exporting RSA keys in DER and PEM format
(Thanks: Legrandin)
* Fix PyCrypto when floor division (python -Qnew) is enabled.
* When building using gcc, use -std=c99 for compilation. This should
fix building on FreeBSD and NetBSD.
