[crypto_core] How are nonces generated? about text

[irungentoo]

It doesn't matter because nonces don't need to be cryptographically random.

Ok, what is the source of the nonces in the current implementation? Is each nonce completely random, or are they generated in some relation to each other? E.g. monotonically increasing or decreasing, fibonacci, or some other function applied to a number of preceding nonces?

Nonces don't need to be cryptographically random in order to have working crypto, but the source does matter because these numbers are passed around in plain text, so knowing how they are generated may expose an attack vector.

All nonces for all parts of toxcore are currently generated the same way so I think this info belongs somewhere other than net_crypto.
