Struct Scrypt

pub struct Scrypt { /* private fields */ }

Main scrypt structure.

Usage:

extern crate dumb_crypto;

use::dumb_crypto::scrypt::Scrypt;

let scrypt = Scrypt::new(1, 128, 1);

let mut out: [u8; 8] = [0; 8];

scrypt.derive(b"passphrase", b"salt", &mut out).unwrap();

assert_eq!(out.to_vec(), vec![
    79, 35, 225, 99, 145, 145, 172, 245,
]);

Implementations

impl Scrypt

pub fn new(r: usize, n: usize, p: usize) -> Self

Create new instance of Scrypt.

Arguments:

• r Block size parameter, must be larger than 1
• n CPU/Memory cost parameter, must be larger than 1, a power of 2 and less than 2 ^ (16 * r)
• p Parallelization parameter, a positive integer less than or equal to (2^32-1) / (4 * r) where hLen is 32 and MFlen is 128 * r.

pub fn derive( self: &Scrypt, passphrase: &[u8], salt: &[u8], out: &mut [u8], ) -> Result<(), ScryptError>

Derive secret string using passphrase and salt.
