bcrypt

Build Status Documentation

Installation

Add the following to Cargo.toml:

bcrypt = "0.7"

The minimum Rust version is 1.34.0

Usage

The crate makes 3 things public: DEFAULT_COST, hash, verify.

extern crate bcrypt;

use bcrypt::{DEFAULT_COST, hash, verify};

let hashed = hash("hunter2", DEFAULT_COST)?;
let valid = verify("hunter2", &hashed)?;

The cost needs to be an integer between 4 and 31 (see benchmarks to have an idea of the speed for each), the DEFAULT_COST is 12.

Benchmarks

Speed depends on the cost used: the highest the slowest. Here are some benchmarks on my 4 years old laptop to give you some ideas on the cost/speed ratio. Note that I don't go above 14 as it takes too long.

test bench_cost_4       ... bench:   1,197,414 ns/iter (+/- 112,856)
test bench_cost_10      ... bench:  73,629,975 ns/iter (+/- 4,439,106)
test bench_cost_default ... bench: 319,749,671 ns/iter (+/- 29,216,326)
test bench_cost_14      ... bench: 1,185,802,788 ns/iter (+/- 37,571,986)

Acknowledgments

This gist for the hash splitting and the null termination.
