| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | to have been so! Change MDx_HashFunction::hash to a new compress_n which hashes an arbitrary number of blocks. I had a thought this might reduce a bit of loop overhead but the results were far better than I anticipated. Speedup across the board of about 2%, and very noticable (+10%) increases for MD4 and Tiger (probably b/c both of those have so few instructions in each iteration of the compression function).

* Last minute es_ftw optimizations / logic changes. Performance of seedinglloyd2008-11-212-35/+27
| | | | | | | | | was too slow, it was noticably slowing down AutoSeeded_RNG. Reduce the amount of output gathered to 32 times the size of the output buffer, and instead of using Buffered_EntropySource, just xor the read file data directly into the output buffer. Read up to 4096 bytes per file, but only count the first 128 towards the total goal (/proc/config.gz being a major culprit - large, random looking, and entirely or almost static).

PK_Signer taking an EMSA* instead of a name. generate_dsa_primes using an Algorithm_Factory Changes to how new algorithms are added (look_add.h is gone entirely, replaced by Algorithm_Factory calls) in xor_ciph. Also update for new stream cipher key schedule function name and new directory for base class decl.

Add ability to explicitly disable using TR1 with --with-tr1=none Add a marker in the cc info files specifiying if TR1 should be chosen by default. Yes, autoconf would be better for this than a static per-compiler setting. Yes, I totally hate autoconf. Yes, I would still consider autoconf patches. No, I'm not going to do it myself. :) I am looking forward to being able to safely adopt C++0x and TR2 throughout the library and make the need for a lot of this special-casing stuff go away. Until then, it seems better to defaulting to using tr1 (and thus, ECC) than not.

* Remove print statements in PointGFp::check_invariants which were triggeredlloyd2008-11-171-19/+0
