Hello,
My software uses DCPCrypt Library for Delphi.
Specifically the following algorithms are used:
AES (Advanced Encryption Standard)
Tiger (192 bit Hash)
I looked at the source code some time ago and it seems it simply use
int64's
which are simply implemented by the delphi compiler with simulated 64 bit
integers/multi-byte arithmetic, which is kinda good because this allows
backwards compatibility.
However newer processors have special instructions like mmx, sse, sse2,
etc.
I wonder if the library can be extended to include special cl*****s which
could be used for newer processor when detected.
So some general questions which I haven't looked into... but later I will
look into it.
For now I ask the people on these newsgroups:
1. Does AES benefit from SSE instruction set ? Can performance be
increased
without comprising security too much. Especially ECB mode ;)
2. Does Tiger benefit from SSE instruction set ? Can it's performance be
increased ?
Thanks for any insight or ideas.
Bye,
Skybuck.
