tpm2-rand

This crate provides a simple rand generator that uses a TPM2 device to generate random numbers. It implements the rand_core::RngCore trait, allowing it to be used seamlessly with the rand ecosystem.

Features

It simply exposes the RNG functionality from the TPM2 device, That's it.

Usage

To use this crate, add the following to your Cargo.toml:

[dependencies]
tpm2-rand = "0"
tss-esapi = "7"

Then, you can use it in your code as follows:

use tpm2_rand::Tpm2Rand;
use tss_esapi::{
    Context,
    TctiNameConf,
};


let context = Context::new(TctiNameConf::from_environment_variable().unwrap()).unwrap();
let mut rng = Tpm2Rand::new(context).unwrap();
let random_bytes = rng.gen::<[u8; 32]>();
println!("Random bytes: {:?}", random_bytes);

You should check out tss-esapi documentation for more details on how to set up the TPM2 context and handle errors.
