pub fn random_request_nonce() -> Result<RequestNonce, CratestackError>Expand description
A fresh Cratestack-Nonce: 16 bytes from the operating system’s CSPRNG.
Fails with CratestackError::Internal if it is unavailable.
The default nonce source of CoseEnvelope::request_nonce,
for a client that sends an unsigned request it wants a verifiable
response to. Here and not on RequestNonce (which cratestack-core
defines) since the second #1006 review (decision B-1): drawing it needs
getrandom, and only this crate selects that crate’s
wasm32-unknown-unknown backend. It replaces 0.13.0’s
RequestNonce::random().
