Generating Randomness

Many applicative use cases are dealing with generating randomness. On klave, randomness generation can be used in the context of query via a true random number generator, and transaction via a pseudo random number generator in order to derive the same randomness on each nodes of the cluster. In both case, this is transparently done in a safe, secure and trustless way (within enclaves, nobody can access, guess or tamper with the random seed).

Generating randomness within Application

To generate randomness within application Klave expose a simple API as part of the SDK.

import { Crypto } from '@klave/sdk';

/**
* @query
*/
export function generateRandomness(): void
{
    // Generate iv
    let iv = Crypto.getRandomValues(12);
}

use klave;

fn generate_randomness(cmd: String){
    let random_bytes = match klave::crypto::random::get_random_bytes(12) {
        Ok(result) => result,
        Err(err) => {
            klave::notifier::send_string(&err.to_string());
            return;
        }
    };
}
