* Move Entropy_Estimator to utils/entropy.h (from anon namespace in HMAC_RNGlloyd2008-11-065-33/+130
| | | | | implementation), remove freestanding estimate_entropy function, change Randpool to use entropy estimator.
* Substantially change Randpool's reseed logic. Now when a reseedlloyd2008-10-274-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | is requested, Randpool will first do a fast poll on each entropy source that has been registered. It will count these poll results towards the collected entropy count, with a maximum of 96 contributed bits of entropy per poll (only /dev/random reaches this, others measure at 50-60 bits typically), and a maximum of 256 for sum contribution of the fast polls. Then it will attempt slow polls of all devices until it thinks enough entropy has been collected (using the rather naive entropy_estimate function). It will count any slow poll for no more than 256 bits (100 or so is typical for every poll but /dev/random), and will attempt to collect at least 512 bits of (estimated/guessed) entropy. This tends to cause Randpool to use significantly more sources. Previously it was common, especially on systems with a /dev/random, for only one or a few sources to be used. This change helps assure that even if /dev/random and company are broken or compromised the RNG output remains secure (assuming at least some amount of entropy unguessable by the attacker can be collected via other sources). Also change AutoSeeded_RNG do an automatic poll/seed when it is created.
* Move EntropySource base class to new entropy_src.h (which allows the ↵lloyd2008-10-262-1/+7

* Move rng.{cpp,h} from core to rng/ topdirlloyd2008-10-267-4/+4
| | | | | | | | | | | | | | 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/

| | | | | | | | | | | | | | | | | | | rather than silently replacing the C++ versions. Instead they are silently replaced (currently, at least) at the lookup level: we switch off the set of feature macros set to choose the best implementation in the current build configuration. So you can have (and benchmark) MD5 and MD5_IA32 directly against each other in the same program with no hassles, but if you ask for "MD5", you'll get maybe an MD5 or maybe MD5_IA32. Also make the canonical asm names (which aren't guarded by C++ namespaces) of the form botan_<algo>_<arch>_<func> as in botan_sha160_ia32_compress, to avoid namespace collisions. This change has another bonus that it should in many cases be possible to derive the asm specializations directly from the original implementation, saving some code (and of course logically SHA_160_IA32 is a SHA_160, just one with a faster implementation of the compression function, so this seems reasonable anyway).
