| | | | | | | | | | | | | random bits. Now they take a reference to a RandomNumberGenerator object. This was applied several times out, so now the constructors to private key objects also take a RandomNumberGenerator& argument. This is also true for a number of randomized algorithms (Miller-Rabin, for instance). You can get a reference to the global PRNG with global_state().prng_reference() This is a provisional thing: and warning: it is not thread safe! If this is a problem instead keep per-thread PRNGs and pass them were needed.

| | | | | | | | | | | | | | | | | | essentially a facade for the RNG object living in the global library state. Rewrite all callers to directly invoke the global state object: this makes it more clear what functions are actually accessing mutable state outside of the normal reference graph (and thus, which functions will have to be altered in order to remove this dependency). Other facades remain in place for the configuration object and the memory allocator factory.
| * The intent of this branch is to remove the global library state objectlloyd2008-04-071-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | (Library_State, in libstate.{h,cpp}). It causes numerous 'interesting' problems with threads, etc, and the best solution here is to move to more or less an object-capability model, where the only objects that a piece of code can access are those which can be referenced through its arguments. First things first, remove the UI 'pulse' code. It is neither necessary nor sufficient for writing proper GUI/event driven code using Botan, has likely never been used in real code, and, given that, causes a distressing amount of overhead in terms of function calls made.
