tor-hspow, equix, hashx: Make all error types Clone2023-07-27T14:20:14ZMicah Elizabeth Scottbeth@torproject.org2023-07-19T20:39:11Zurn:sha1:f4939a5fd87a7b23f20e4aec5ea827feccf9c612
This uses an Arc to hold std::io::Error for low-level HashX runtime
errors.

Reimplement HashX in Rust2023-07-27T14:20:06ZMicah Elizabeth Scottbeth@torproject.org2023-06-28T21:59:46Zurn:sha1:a8756f2bce9f0dba8e445baae82aab90aa9ad096
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.
