Function pbkdf2_into 

pub fn pbkdf2_into<H: Hash>(
    password: &[u8],
    salt: impl Salt<NonEmpty>,
    iters: Iters,
    out_key: &mut [u8],
) -> Result<(), Unspecified>

Performs PBKDF2 and writes the result into the provided out_key buffer.

Arguments

• password - The password to use for the key derivation.
• salt - The salt to use for key derivation.
• iters - The number of times to process the hash.
• out_key - The buffer to write the generated key into.

Errors

• The length of the password was greater than i32::MAX.
• The length of the salt was greater than i32::MAX.
• The number of iters was greater than i32::MAX.
• The length of the out_key was greater than i32::MAX.

FIPS Errors

If the allow-non-fips feature flag is disabled this will return an error if the out_key length is not at least FIPS_MIN_KEY (14 bytes).

Example

use wolf_crypto::kdf::{pbkdf2_into, Sha256, Iters};

let password = b"my secret password";
let salt = [42; 16];
let iters = Iters::new(600_000).unwrap();
let mut out_key = [0u8; 32];

pbkdf2_into::<Sha256>(password, salt, iters, out_key.as_mut_slice()).unwrap();
