* Use `OsRng` in place of `thread_rng`.
This changes the defaults of any builder by instantiating an `OsRng` instead of
a `thread_rng`, the former being much more secure than the latter.
Additionally, all the unit tests that still instantiate RNGs manually used `OsRng`s
as well; while there is no actual need for this level of security in tests, the performance overhead is very small and random number generation complexity has such a small impact on these tests that the convenience of being able to ban `thread_rng` from the codebase altogether, setting a good example and avoid issues when refactoring later greatly outweigh the negatives.
* Instead of storing random number generators in the various consensus algorithm instances, pass them in from the outside whenever they are needed.
This changes a large amount of interfaces (and in this commit is only partially done, since `DistAlgorithm` needs to be fundamentally altered as well.
It also obsoletes parts of the `util` module.
* Added an `R: Rng` type parameter to both methods of `DistAlgorithm`, forcing callers to pass in their own Rngs.
* Fixed documentation grammar and spelling in some of the altered interfaces due to RNG refactoring.
* Move `rng` argument to the end of the argument for most functions.
Also includes a reformatting due to Rust 1.30.
* Updated tests, accomodate `rng`-API changes.
* Fixed remaining compilation issues with new RNG code.
* Fix illegal `self` import outside curly braces.
* Cleaned up comments and fixed broken definition of `broadcast_input`.
* Updated existing test cases to properly work with static dispatch randomness.
* Do not use boxed `Rng`s for key generation in test networks.
* Use the passed-in `Rng` in `ReorderingAdversary`, instead of storing a boxed one.
* Fixed clippy lints after refactoring.
* Removed some no-longer necessary manual `fmt::Debug` implementations in test framework.
* Use `OsRng` even in tests in `binary_agreement_mitm`.
* Use a proper deterministic RNG in tests `binary_agreement_mitm`.
* Refactor `examples/simulation.rs` by not using `ThreadRng`, passing generic `Rng` parameters throughout and using a type alias instead of a newtype as the `Transaction`.
* Remove `thread_rng` use from `examples/node.rs`.
* Explicitly construct `InternalContrib` in `DynamicHoneyBadger::propose`.
* Fixed typo in description of `DistAlgorithm` trait.
This includes a threshold signature in each batch that can be used as a
pseudorandom value.
Also moves `EncryptionSchedule` from `threshold_decrypt` to
`honey_badger`.
Using `hbbft` in other software that is based on frameworks like [tokio](https://tokio.rs), being `Send` is often a requirement on shared data structures.
* Add support for RNG instantiation in proptests.
* Use `proptest` module strategy to create the rng for `net_dynamic_honey_badger`.
* Use seed generation instead of RNG instantiation in tests.
* Remove fixed RNG in `generate_map`.
* `VirtualNet` now supports setting the random generator through the builder.
* Add missing `time_limit` field to `::std::fmt::Debug` trait implementation on `NetBuilder`.
* Pass an instantiated random number generator through `NewNodeInfo` as a convenience.
* Make the random number generator of `DynamicHoneyBadgerBuilder` configurable, at the cost of now requiring mutability to call `build_first_node()`.
* Ensure RNGs are derive from passed in seed in `net_dynamic_hb` tests.
* Correct inappropriate use of `random::Random` instead of `Rng::gen` to generate dependent values in `binary_agreement`.
The original implementation used `rand::random()`, which will always use the `thread_rng`, ignoring the fact that an RNG has actually been passed in.
* Do not use `OsRng` but passed in RNG instead.
* Use reference/non-reference passing of rngs more in line with the `rand` crates conventions.
* Document `rng` field on `DynamicHoneyBadger`.
* Make `SyncKeyGen` work with the extend (`encrypt_with_rng`) API of `threshold_crypto`.
* Use passed-in random number generator in `HoneyBadger`.
* Create `SubRng` crate in new `util` module to replace `create_rng()`.
* Use an RNG seeded from the configure RNG when reinitializing `DynamicHoneyBadger`.
* Use the correct branch of `threshold_crypto` with support for passing RNGs.
* spam protection part 1: remote epoch tracking in HoneyBadger
* moved handling of EpochStarted out of EpochState
* allowed EpochStarted from observers
* removed an unnecessary function call
* updated formatting to beta
* removed an unnecessary variable
* Remove unnecessary recursive method calls.
* Add `handle_message` (without the trait).
* Fix a bug where `handle_message_content` would create an `EpochState`
with the wrong number.
