Andreas Fackler 51b87b8bae Add node transaction messages to Dynamic HB. 2018-07-30 23:52:34 +01:00
Andreas Fackler c0cef3b50b Avoid redundant key computations. 2018-07-30 23:52:34 +01:00
Andreas Fackler e3a401bcb9 Make SyncKeyGen NodeUid-aware. 
This allows the caller to address nodes by ID instead of by index.

Also contains a few other minor changes that will be needed for
`DynamicHoneyBadger`.

Vladimir Komendantskiy 17fdffa90f threshold encryption of proposals in HoneyBadger 2018-07-30 23:52:34 +01:00
Andreas Fackler 0c66e16010 Remove generic E: Engine from crypto. 2018-07-30 23:52:34 +01:00
Andreas Fackler 81cbe5a63b Implement SyncKeyGen. 
This is a _synchronous_ key generation algorithm. We will use it in
`DynamicHoneyBadger`, on top of `HoneyBadger` to satisfy the synchrony
requirements.

It can also be used independently e.g. on top of a blockchain.

Peter van Nostrand 1c3afe85eb Fix formatting. 2018-07-30 23:52:34 +01:00
Peter van Nostrand 5bf57d5d1d Added clear-on-drop secret-keys to 'NetworkInfo'. 2018-07-30 23:52:34 +01:00
Andreas Fackler 34d642f709 Improve Hash impl for Ciphertext. 
This formulation makes it harder to forget updating the `Hash`
implementation if the `Ciphertext` type changes.
 2018-07-30 23:52:34 +01:00
Andreas Fackler db1de60237 Implement Hash for "public" cryptographic types. 
This adds a `Hash` implementation for public keys, commitments,
ciphertexts and signatures — types that might make sense to be included
in special transactions. The `DynamicHoneyBadger` implementation will
require some of them.

Andreas Fackler cf1782b2cf Simplify serde implementations, add Ciphertext. 2018-07-30 23:52:34 +01:00
Andreas Fackler db2d84cabd Support serde by default. 
This removes the `serialization-serde` feature, since serde is already
used internally and therefore a dependency anyway.
