EntropyRng

Struct EntropyRng 

Source
pub struct EntropyRng { /* private fields */ }
Expand description

A RngCore view over a Source, for crates that generate keys themselves.

ssh-key and the certificate path take an RNG rather than bytes, so the mixing has to reach them through this rather than being applied afterwards.
