| | | | | | | | | | | | | | | | | | | | | | | | | | | | This, I think, was what was causing the OpenSSL AES code to crash (without a key being set, the rounds are unset and probably causes the code to loop out past the end of an array somewhere). Sadly, this also confirms that OpenSSL's AES is much faster than Botan's: AES-128: 115.032 [core] 152.994 [openssl] AES-192: 98.6724 [core] 130.087 [openssl] AES-256: 86.6348 [core] 113.608 [openssl] Definitely some improvement can be made there! :(

Defaults to 8 blocks for all modes, which is sufficient that any likely parallelism can be extracted (via SIMD or concurrent execution) but not so much as to seem likely to cause cache problems (8*128 bits = 128 bytes, or two x86 cache lines)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | decryption. Currently only used for counter mode. Doesn't offer much advantage as-is (though might help slightly, in terms of cache effects), but allows for SIMD implementations to process multiple blocks in parallel when possible. Particularly thinking here of Serpent; TEA/XTEA also seem promising in this sense, as is Threefish once that is implemented as a standalone block cipher.
