  use pow_sha256::{ConfigBuilder, PoW};

  fn main() {

      let phrase = "ironmansucks";

      const DIFFICULTY: u32 = 1000;

      assert!(config.is_valid_proof(&work, &phrase));

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
