Std.Crypto.newNonce

fn

This is a callable function.

What it does

A fresh nonce of the length `seal` needs, from the same secure source.

Drawn rather than counted, so a program sealing many messages under one key

repeats a nonce only with vanishing probability instead of by a bookkeeping

mistake.

Read the signature
