pub fn random<B: AsMut<[u8]>>(buf: B) -> Result<()>Expand description
Fills the given buffer with random data.
Fills the given buffer with random data produced by a
cryptographically secure pseudorandom number generator (CSPRNG).
The output may be used as session keys or to derive long-term
cryptographic keys from. However, to create session keys,
consider using SessionKey::new.
