| * | Reimplement Equi-X in RustMicah Elizabeth Scott2023-07-2714-0/+1727
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a new pure Rust implementation of the Equi-X algorithm designed by tevador for Tor's onion service proof of work puzzle v1. Equi-X is an asymmetric puzzle algorithm based on Equihash, with N=60, K=3, the XOR replaced with modular addition, a 16-bit index space, and HashX as the inner hash function.

| * | Reimplement HashX in RustMicah Elizabeth Scott2023-07-2720-26/+4015
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a new pure Rust implementation of the HashX algorithm designed by tevador for Tor's onion service proof of work puzzle v1. HashX is a lightweight family of randomly generated hash functions. A seed, via blake2 and siphash, drives a program generation model which randomly selects opcodes and registers while following some constraints that avoid timing stalls or insufficient hash mixing. The execution of these hash funcions can be done using a pure Rust interpreter, or about 20x faster using a very simple just in time compiler based on the dynasm assembler crate. This has been implemented for x86_64 and aarch64. Signed-off-by: Micah Elizabeth Scott <[email protected]>

| * | tor-proto: Add functions for handling Shutdown and AddFakeHop messages.Gabriela Moldovan2023-07-261-42/+37
| | | | | | | | | | | | | | | This helps reduce code duplication, as `CtrlMsg::Shutdown` and `CtrlMsg::AddFakeHop` are now handled in multiple places.
| * | tor-proto: Extract first-hop creation to a separate function.Gabriela Moldovan2023-07-261-37/+11
| | | | | | | | | | | | | | | | | | I think it's safe to handle `ChanMsg::Create` separately, because there's nothing for the reactor to do until the first hop of the circuit is created (so blocking on this _should_ be alright).
| * | tor-proto: Create a function for handling the initial CREATE cell.Gabriela Moldovan2023-07-261-1/+89
| | | | | | | | | | | | | | | | | | This logic from `create_firsthop()` was extracted (copied) from `Reactor::run_once()`. A future commit will update `Reactor::run_once()` to use `create_firsthop()`.
