QUESTION

Rng getting randomness from operating system vs crypto rng's

Asked 2022-Feb-09 at 20:35

this is a question that does have a lot of overlap with what might be posted on cryptography stack exchange,but it's mostly Rust-specific, and thus I posted it here.

So I have an application that needs to use a DH keypair.

It's important that this project is academic only, this code will not be used in any prod environments.

I'm working in a context that already uses a crate called x25519_dalek and thus it makes sense to keep using that resource for my own creation of keypairs.

The documentiation gives this example of key creation:

OsRng should be cryptographically secure. It implements CryptoRng, which is a trait only implemented for cryptographically secure PRNGs, and it's backed by the getrandom crate, which always uses the system's (or, in the case of WebAssembly, the environment's) CSPRNG.

It is always a sensible choice for a CSPRNG, but as mentioned in the comments, it isn't always very fast, since it involves a system call per operation, and the system's CSPRNG isn't always very fast, either. In such a case, you can use ThreadRng, which will be faster and is also cryptographically secure.
