Andreas Fackler 7a0b397233 Add node transaction messages to Dynamic HB. 2018-07-02 14:14:19 +02:00
Andreas Fackler 2b4f77f11c Avoid redundant key computations. 2018-06-27 14:47:05 +02:00
Andreas Fackler 062b35ab3a 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 c7f4994e3a threshold encryption of proposals in HoneyBadger 2018-06-22 10:12:38 +01:00
Andreas Fackler e11f183db2 Remove generic E: Engine from crypto. 2018-06-22 10:08:23 +02:00
Andreas Fackler 7eb487f329 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 73368b7a32 Fix formatting. 2018-06-21 13:06:48 -04:00
Peter van Nostrand 05da712c20 Added clear-on-drop secret-keys to 'NetworkInfo'. 2018-06-21 12:08:48 -04:00
Andreas Fackler a47123c4dd Improve Hash impl for Ciphertext. 
This formulation makes it harder to forget updating the `Hash`
implementation if the `Ciphertext` type changes.
 2018-06-20 22:09:43 +02:00
Andreas Fackler 1f27fa6891 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 6484242afc Simplify serde implementations, add Ciphertext. 2018-06-20 10:43:59 +02:00
Andreas Fackler 83f8d61402 Support serde by default. 
This removes the `serialization-serde` feature, since serde is already
used internally and therefore a dependency anyway.
