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: u32 = 1000;

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

Modules

• dev

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.

Enums

• ConfigBuilderError
  Error type for ConfigBuilder
• IncrementalSolve
  Return value of incremental prooving. When proof is ready, IncrementalSolve::Work is returned and when proof is not ready, IncrementalSolve::Intermediate is returned
• PoWBuilderError
  Error type for PoWBuilder
