* Remove pointless 'error' attribute from stream ciphersDwayne Litzenberger2013-07-141-6/+1
| | | | | Many years ago, this was removed from block_template, but not from stream_template.
* Add ABI check when importing _counter from block_templateDwayne Litzenberger2013-07-143-0/+26

* Counter: Deprecate disable_shortcut; Remove __PCT_CTR_SHORTCUT__ entirelyDwayne Litzenberger2013-07-143-22/+4
| | | | | | | | | | | | The `disable_shortcut` option served as a workaround in case `__PCT_CTR_SHORTCUT__` leaked through a wrapper object, but I don't think anyone actually used it, and it was a bad idea to expose it as part of the public API. Now that we do strong type checking inside block_template.c, there shoujld be no need to ever use this option. It's now a no-op, retained for backward compatibility only. It will be removed in some future version of PyCrypto.
* Fix MODE_CTR memory leak under Python 3Dwayne Litzenberger2013-07-142-18/+34
| | | | | | | | | The leak arose from the string creation in this line: PyObject_HasAttr(counter, PyUnicode_FromString("__PCT_CTR_SHORTCUT__")) This commit replaces the __PCT_CTR_SHORTCUT__ hack with code that imports the _counter module and checks the appropriate types.
* AES-NI support: Python 2.1 Backward compatibilityDwayne Litzenberger2013-04-211-1/+4
| | | | | - METH_NOARGS was introduced in Python 2.2. - Python 2.1 doesn't have True and False builtins.

* Include inttypes.h or sys/inttypes.h based on what autoconf tells usDwayne Litzenberger2013-04-215-20/+26
| | | | | This should fix compilation on HP-UX 11.31. Thanks Adam Woodbeck for reporting this.
* Hash: Speed up initialization by removing pure-Python wrappershash-speedup-wipDwayne Litzenberger2013-02-178-36/+136
| | | | | | | | | | | | The pure Python wrappers around Crypto.Hash.* were convenient, but they slowed down hash initialization by 4-7x. There is a speed trade-off here: The MD5 and SHA1 objects are just wrapped hashlib objects (or old-style md5/sha objects). To maintain API compatibility with the rest of PyCrypto, we still have to wrap them, so they're slower to initialize than the rest of the hash functions. If hashlib ever adds a .new() method, we will automatically use hashlib directly and gain the initialization speed-up.
* Hash: Remove "oid" attributes; add "name" attributeDwayne Litzenberger2013-02-178-0/+11
| | | | | | | | | | | | In PyCrypto v2.5, the "oid" attribute was added to hash objects. In retrospect, this was not a good idea, since the OID is not really a property of the hash algorithm, it's a protocol-specific identifer for the hash functions. PKCS#1 v1.5 uses it, but other protocols (e.g. OpenPGP, DNSSEC, SSH, etc.) use different identifiers, and it doesn't make sense to add these to Crypto.Hash.* every time a new algorithm is added. This also has the benefit of being compatible with the Python standard library's "hashlib" objects, which also have a name attribute.
* Counter: Fix compiler warning about signed-unsigned comparisonDwayne Litzenberger2013-02-172-1/+2
|
* Fix compiler warning about "_POSIX_C_SOURCE" being redefined in string.hDwayne Litzenberger2013-02-1713-12/+16
| | | | The solution is to include Python.h before string.h is included.
* Fix leaks in _fastmathSebastian Ramacher2013-02-161-2/+3
| | | | | | | Fix leaks in getRandomInteger and rsaKeyNew. If randfunc throws an exception they both don't clean up properly. Thanks to Andreas Stührk for helping me to debug these two leaks.
* SHA2: Don't export symbol 'add_length'Dwayne Litzenberger2013-02-111-1/+1
| | | | | | Exporting symbols can cause symbol conflicts with external libraries, causing the dynamic linker to silently pick one of the implementations, which can lead to subtle bugs if they're actually different functions.
* setup.py: Add more compiler warnings and fix unsigned-signed comparisonsDwayne C. Litzenberger2012-07-032-4/+4
|
* _fastmath: Replace 'long int' with 'long' to avoid confusionDwayne C. Litzenberger2012-07-031-12/+12
| | | | | "long int" is equivalent to "long" in C, and it's harder to misread it as "int" this way.
* _fastmath: Use default false_positive_prob is one is not specifiedDwayne C. Litzenberger2012-07-031-1/+1
| | | | This should never happen, but the behaviour is saner if it does.

|
* Store result of rabinMillerTest in an int.Sebastian Ramacher2012-07-031-2/+2
| | | | | rabinMillerTest returns an int but getStrongPrime stores the result in an unsigned long int which makes the tests in line 1545 and 1621 useless.

| | | | | | | A new module (blockalgo) has been added. It contains a class (BlockAlgo) all ciphers derive from. The only purpose of such base class is to centralize all general documentation applicable to all block ciphers (e.g. modes) into a single file.

* _fastmath: missing Py_BLOCK_THREADS on isPrime(1)Dwayne C. Litzenberger2012-04-251-2/+5
| | | | | | | | | | When _fastmath is present, the following code caused the Python interpreter to abort with a fatal error: from Crypto.Util.number import isPrime isPrime(1) # Fatal Python error: PyEval_SaveThread: NULL tstate Bug report: https://bugs.launchpad.net/pycrypto/+bug/988431
* Fix segfault if Crypto.Random.new is missing for some reason.Dwayne C. Litzenberger2012-02-181-0/+5
| | | | | | | This should never happen, but we're already checking that Crypto.Random.new is callable, so we might as well also check that Crypto.Random.new exists. Also, fixing this should silence an (arguably false-positive) error emitted by cpychecker (a static analysis tool used by the Fedora project).
