NodeRng

Struct NodeRng 

Source
pub struct NodeRng(/* private fields */);
Expand description

ChaCha20 CSPRNG adapter implementing the rand 0.10 traits the MAC requires (Platform::Rng: rand::CryptoRng). Seeded once at boot from the board’s hardware TRNG, exactly like the session’s IdentityRng, while that source is still ours to read.
