* Check in an initial implementation of CBC-MAC.lloyd2007-09-161-0/+36
| | | | | | | The test vectors were generated by Crypto++ 5.5 on a Linux/x86-64 machine. Test vectors for CBC-MAC(DES) all pass, for inputs up to 63 bytes. For CBC-MAC(AES-128), all test vectors with inputs over 10 bytes fail to verify against what Crypto++ produces. Unknown at this time where the bug lies.

* If an algorithm cache lookup fails, index the newly created prototype objectlloyd2007-07-171-6/+10
| | | | | | | | | | | | | | | | | | | | | under the name that the algorithm was originally requested by. This enables proper caching for algorithm names which deref_alias fails to fully dereference such as "HMAC(SHA-1)". The previous code had two major problems with names of that type, firstly that the cache was effectively bypassed due to all prototype objects in Algorithm_Cache_Impl being indexed by their canonical names rather than the alias that they were requested under, and that there existed a race condition where a prototype object might be deleted while in use in multithreaded code. The downside of this change is that using multiple names to refer to a single algorithm causes multiple prototype objects to be created, one for each name that is in use. However the memory overhead of this should be fairly minimal and given the severity of the race condition this seems like a worthwhile tradeoff. A more complete fix would be to fix deref_alias to properly derference all alias names. That fix would be complimentary with this change in that if deref_alias handled all names properly there would be a single prototype object and there would then be no additional memory overhead to the cache.

| | | | | | | | | | | | | | | | | | into account endian differences. The current code does not take advantage of the knowledge of which endianness we are running on; an optimization suggested by Yves Jerschow is to use (unsafe) casts to speed up the load/store operations. This turns out to provide large performance increases (30% or more) in some cases. Even without the unsafe casts, this version seems to average a few percent faster, probably because the longer loading loops have been partially or fully unrolled. This also makes the code implementing low-level algorithms like ciphers and hashes a bit more succint.

* Do not allocate a block of memory in Pooling_Allocator::init(); this waslloyd2006-09-201-1/+0
