hash-cpu-bench

Recently, while writing a registration system for my backend project, I decided to use argon2 to hash passwords. And when I ran test requests on my backend, I was a bit surprised to see that it took me 600ms to hash through argon2. Then my friend ran argon2 hashing on his PC and the identical hashing took 25ms. From this I realized that my processor was crap, but still I wanted to make a CLI benchmark tool based on hash functions.

Supported Algorithms

Algorithm	Parameters
Argon2idFast	m=64MB, t=2, p=1
Argon2idSecure	m=256MB, t=4, p=2
Argon2i	m=128MB, t=3, p=1
Argon2d	m=128MB, t=3, p=1
Bcrypt	cost=10
Bcrypt	cost=12
Bcrypt	cost=14

Building

Note

You must have Rust installed on your computer.

git clone https://github.com/smokingplaya/hash-cpu-bench
cd hash-cpu-bench
cargo build --release

Tip

The executable binary will be placed in ./target/release/hash-cpu-bench(.exe in Windows)

Interactive Mode

You can use the CLI interactively to hash strings on-the-fly and see the results instantly:

hash-cpu-bench

Features

• Select a hashing preset interactively:

Choose hashing preset (Argon2idFast, Argon2idSecure, Argon2i, Argon2d, Bcrypt10, Bcrypt12, Bcrypt14)
preset> Argon2idFast

• Hash any input by typing it:

> mypassword123
Argon2idFast: $argon2id$v=19$m=65536,t=2,p=1$... (659ms)

• Change the hashing preset at any time:

> preset Bcrypt12
Preset changed to Bcrypt12

• Exit the REPL:

> exit

Benchmark

Run a full benchmark of all supported hash algorithms:

hash-cpu-bench --benchmark

By default, the benchmark will perform 15 iterations per algorithm and save results to ./bench_<timestamp>.json

Options

• --alg <ALGORITHM> - Run benchmark only for the specified algorithm (e.g., Argon2idFast, Argon2i, Bcrypt10).

hash-cpu-bench --benchmark --alg Argon2idFast

• --repeats <N> - Set the number of iterations per algorithm (default: 15).

hash-cpu-bench --benchmark --repeats 20
