BCrypter

A pure rust implementation of the bcrypt hashing function based on the Blowfish cipher. Currently only running on nightly builds. Full API documentation can be found here

Installation

In your Cargo.toml file:

toml [dependencies] bcrypter = "0.1.1"

Usage

Basic hash

```rust extern crate bcrypter; use bcrypter::password;

let pw = "hunter2".tostring(); let result = password(pw).hash().unwrap(); let bcrypthashstring = result.hashstring; ```

Custom cost

rust let result = password(pw) .cost(6) .hash() .unwrap();

Custom salt

rust let salt = [0u8; 16]; let result = password(pw) .salt(salt) .cost(8) .hash() .unwrap();

Verify password

rust let known_hash = "$2a$04$7eAf8viXin8zazyvaU2HLuZGEbvaHy/lsnlG.HFWkBST5irHhXKJO".to_string(); let correct_password : bool = password(pw) .verify(known_hash) .unwrap()

Raw digest

rust let result = password(pw).hash().unwrap(); let digest_bytes : [u8: 24] = result.digest;

Notes

• The default cost is 12

• A random 16 byte array is used when no salt parameter is provided.

• The maximum password input is 72 bytes, anything over that will be truncated rather than raise an error. If you need larger inputs consider hashing it beforehand.
