Function etebase::utils::randombytes_deterministic

pub fn randombytes_deterministic(size: usize, seed: &[u8; 32]) -> Vec<u8> 

Return a buffer filled with deterministically cryptographically random bytes

This function is similar to randombytes but always returns the same data for the same seed. Useful for testing purposes.

Arguments:

• seed - the seed to generate the random data from
• size - the size of the returned buffer (in bytes)

Examples

use etebase::utils::randombytes_deterministic;

let seed = [42; 32];

// Equal seeds produce equal sequences, regardless of length
let a = randombytes_deterministic(10, &seed);
let b = randombytes_deterministic(5, &seed);

assert_eq!(a[..5], b);

// Different seeds produce different sequences
let c = randombytes_deterministic(10, &[0; 32]);

assert_ne!(a, c);
assert_eq!(c, &[5, 67, 208, 128, 105, 110, 24, 70, 104, 100]);
