Struct pwbox::ScryptParams

pub struct ScryptParams { /* fields omitted */ }

Scrypt key derivation function parameterized as per the original paper.

Serialization

The function is serialized as three fields: n, r and p. See the Scrypt paper for more details on what they mean.

use serde_json::json;

let scrypt = Scrypt::default();
assert_eq!(
    serde_json::to_value(scrypt).unwrap(),
    json!({ "n": 16384, "r": 8, "p": 1 })
);

Implementations

impl ScryptParams

pub const fn light() -> Self

Returns "light" scrypt parameters as used in Ethereum keystore implementations.

n = 2^12, r = 8, p = 6.

pub const fn custom(log_n: u8, p: u32) -> Self

Creates custom parameters for scrypt KDF.

The r parameter is always set to 8 as per libsodium conversion from opslimit / memlimit and per Ethereum keystore implementations.
