* Hash: Speed up initialization by removing pure-Python wrappershash-speedup-wipDwayne Litzenberger2013-02-1721-845/+274
| | | | | | | | | | | | 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: Generic Crypto.Hash.new(algo, [data]) functionDwayne Litzenberger2013-02-172-0/+154
| | | | | This allows us to instantiate a new hash given only an existing hash object.
* Hash: Remove "oid" attributes; add "name" attributeDwayne Litzenberger2013-02-1720-103/+92
| | | | | | | | | | | | 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.

* Hash: Rename SHA->SHA1 and RIPEMD->RIPEMD160 (pct-speedtest.py)Dwayne Litzenberger2013-02-171-2/+7
| | | | Oops, I missed this one.
* Hash: Rename SHA->SHA1 and RIPEMD->RIPEMD160 (2/2)Dwayne Litzenberger2013-02-162-0/+48
| | | | | | | | | These algorithm names were confusing, because there are actually algorithms called "SHA" (a.k.a. SHA-0) and "RIPEMD" (the original version). This commit adds backward-compatibility support for the old Crypto.Hash.SHA and Crypto.Hash.RIPEMD modules.
* Hash: Rename SHA->SHA1 and RIPEMD->RIPEMD160 (1/2)Dwayne Litzenberger2013-02-1617-55/+60
| | | | | | | | | These algorithm names were confusing, because there are actually algorithms called "SHA" (a.k.a. SHA-0) and "RIPEMD" (the original version). This commit just renames the modules, with no backward-compatibility support.

* Use autoconf to generate compiler optionsDwayne Litzenberger2013-02-1614-137/+2942
| | | | | | | Hopefully this means we'll break on fewer platforms. Also, remove some of the extra optimization flags (e.g. -O3 -fomit-frame-pointer), which don't really do much.

* Fix random.shuffle SelfTestDwayne Litzenberger2013-02-161-1/+1
| | | | | | random.shuffle("1") is a no-op, so it doesn't raise TypeError. This is now true of both the stdlib random.shuffle and PyCrypto's random.shuffle implementation.
* Fix LP#1061217: random.shuffle takes O(n^2) timeDwayne Litzenberger2013-02-161-7/+7
| | | | | | | | | | | The previous implementation took O(n**2) time and O(n) auxiliary space. We now use the Fisher-Yates algorithm, which takes O(n) time and O(1) space. Thanks to Sujay Jayakar and Andrew Cooke for pointing this out and suggesting a solution. Bug report: https://bugs.launchpad.net/pycrypto/+bug/1061217
* 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.

| | | | | On my machine, hashlib is about 5x faster than PyCrypto for single-block inputs. :( (It's about the same for long inputs.)

* 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.

| * Using MODE_CBC instead of MODE_ECB in README exampleAnton Rieder2012-06-161-3/+3
| | | | | | | | | | | | | | | | | | ECB mode has known disadvantages and while the use of it could be intended, I think it would be a good idea to have a 'stronger' mode in the example. Thus, I adopted the example in the README to make use of MODE_CBC instead of MODE_ECB.
