| | | | | | | | | | in a reasonable way. Low on features, which is rather intentional. There is a version code included in the format so further extensions are possible, if warranted. Inspired by the n-th mailing list request for such a class. Realized it was probably better that I design such code than random people who just want 'something that works'.

* Check in a branch with a major redesign on how entropy polling is performed.lloyd2009-01-271-16/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Combine the fast and slow polls, into a single poll() operation. Instead of being given a buffer to write output into, the EntropySource is passed an Entropy_Accumulator. This handles the RLE encoding that xor_into_buf used to do. It also contains a cached I/O buffer so entropy sources do not individually need to allocate memory for that with each poll. When data is added to the accumulator, the source specifies an estimate of the number of bits of entropy per byte, as a double. This is tracked in the accumulator. Once the estimated entropy hits a target (set by the constructor), the accumulator's member function predicate polling_goal_achieved flips to true. This signals to the PRNG that it can stop performing polling on sources, also polls that take a long time periodically check this flag and return immediately. The Win32 and BeOS entropy sources have been updated, but blindly; testing is needed. The test_es example program has been modified: now it polls twice and outputs the XOR of the two collected results. That helps show if the output is consistent across polls (not a good thing). I have noticed on the Unix entropy source, occasionally there are many 0x00 bytes in the output, which is not optimal. This also needs to be investigated. The RLE is not actually RLE anymore. It works well for non-random inputs (ASCII text, etc), but I noticed that when /dev/random output was fed into it, the output buffer would end up being RR01RR01RR01 where RR is a random byte and 00 is the byte count. The buffer sizing also needs to be examined carefully. It might be useful to choose a prime number for the size to XOR stuff into, to help ensure an even distribution of entropy across the entire buffer space. Or: feed it all into a hash function? This change should (perhaps with further modifications) help WRT the concerns Zack W raised about the RNG on the monotone-dev list.
* Add test_es, a program that polls each enabled entropy source (both fastlloyd2008-11-251-0/+101

| | | | | | | | | | | | out of tree builds. Also rename the generated botan-config script so that it is, like the pkg-config settings, namespaced by the major and minor version numbers (eg, botan-17-config). This is useful in particular for distros like Debian which ship both stable and unstable versions. Currently Debian is actually the only distro I know of shipping 1.7 as well as 1.6, but I would certainly like to encourage more in the future by making it easy to do.
* Move rng.{cpp,h} from core to rng/ topdirlloyd2008-10-2621-79/+63
| | | | | | | | | | | | | | Add a new class AutoSeeded_RNG that is a RandomNumberGenerator that wraps up the logic formerly in RandomNumberGenerator::make_rng. make_rng in fact now just returns a new AutoSeeded_RNG object. AutoSeeded_RNG is a bit more convenient because - No need to use auto_ptr - No need to dereference (same syntax everywhere - it's an underestimated advantage imo) Also move the code from timer/timer_base to timer/

Also reindent the code to match more or less the convention in the rest of the codebase. At this point all ECDSA tests are pasing. (That probably just means there aren't enough ECDSA tests)
