Crate pow_sha256

MCaptch's SHA256 based Proof of Work library

Example:

  use pow_sha256::{ConfigBuilder, PoW};

  fn main() {
      let config = ConfigBuilder::default()
        .salt("myrandomsaltisnotlongenoug".into())
        .build()
        .unwrap();

      let phrase = "ironmansucks";

      const DIFFICULTY: u128 = u128::MAX / 32;

      let work = config.prove_work(&phrase, DIFFICULTY).unwrap();
      assert!(config.calculate(&work, &phrase).unwrap() >= DIFFICULTY);
      assert!(config.is_valid_proof(&work, &phrase));
      assert!(config.is_sufficient_difficulty(&work, DIFFICULTY));
  }    

Structs

Config	Configuration for generting proof of work Please choose a long, unique value for salt Resistance to dictionary/rainbow attacks depend on uniqueness of the salt
ConfigBuilder	Builder for Config.
PoW	Proof of Work over concrete type T. T can be any type that implements serde::Serialize.
PoWBuilder	Builder for PoW.
