bcrypt
Installation
Add the following to Cargo.toml:
= "0.3"
The minimum Rust version is 1.25
Usage
The crate makes 3 things public: DEFAULT_COST
, hash
, verify
.
extern crate bcrypt;
use ;
let hashed = hash?;
let valid = verify?;
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)
