* Add ; after call to VC++'s __cpuid, not a macrolloyd2009-10-251-1/+1

* Cast the u32bit output array to an int* when calling the VC++ intrinsic,lloyd2009-10-251-3/+6
| | | | | | | since it passes signed ints for whatever reason. Ensure CALL_CPUID is always defined (previously, it would not be if on an x86 but compiled with something other than GCC, ICC, VC++).

* Use new load/store ops in xtea x4 codelloyd2009-10-231-12/+6

* Add new store_[l|b]e variants taking 8 values.lloyd2009-10-231-16/+108
| | | | | | Add new load options that are passed a number of variables by reference, setting them all at once. Will allow for batching operations (eg using SIMD operations to do 128-bit wide bswaps) for future optimizations.
* Simply unrolling the loop in XTEA and processing 4 blocks worth of data atlloyd2009-10-231-0/+70
| | | | | | | | a time more than doubles performance (from 38 MB/s to 90 MB/s on Core2 Q6600). Could do even better with SIMD, I'm sure, but this is fast and easy, and works everywhere. Probably will hurt on 32-bit x86 from the register pressure.
* Increase the internal buffer size of the Hex coder/decoder, and put it intolloyd2009-10-231-3/+5
| | | | | | | | | | | | | | a named constant instead of being magic. Move from 64 bytes to 256. This was necessary to allow Pipe(new Hex_Decoder, filter, ...) to give filter a sufficiently large input block. It would be nicer if the filter itself (in this case, ECB_Decryption, but others apply as well) was smart enough to buffer on its own. It might also be useful if code could query what parallelism a block cipher provided and modify their actions accordingly.
* Remove all exception specifications. The way these are designed in C++ islloyd2009-10-22121-140/+140
| | | | | | just too fragile and not that useful. Something like Java's checked exceptions might be nice, but simply killing the process entirely if an unexpected exception is thrown is not exactly useful for something trying to be robust.

| | | | | | | | | | | | | | | | | | | | | | | | | | Remove encrypt, decrypt - replace by cipher() and cipher1() Remove seek() - not well supported/tested, I want to redo with a new interface once CTR and OFB modes become stream ciphers. Rename resync to set_iv() Remove StreamCipher::IV_LENGTH and add StreamCipher::valid_iv_length() to allow multiple IV lengths (as for instance Turing allows, as would Salsa20 if XSalsa20 were supported).

| | | | | | | | | | | | | | | | the prefetch is called for each block of input, and so a total of (4096+256)/64 = 68 prefetches are executed for each block. This reduces performance of iterative modes dramatically. I'm not sure what the right approach for dealing with this is.

| * Use prefetching in AES. Nominally, this will help somewhat with preventinglloyd2009-09-291-0/+8
| | | | | | | | | | | | | | | | | | | | timing attacks, since once all the TE/SE tables are entirely in cache then timing attacks against it become somewhat harder. However for this to be a full defense it would be necessary to ensure the tables were entirely loaded into cache, which is not guaranteed by the normal SSE prefetch instructions. (Or prefetch instructions for other CPUs, AFAIK). Much more importantly, it provides a 10% speedup.
