The insecure-seed interface for seeding hash-map DoS resistance.
It is intended to be portable at least between Unix-family platforms and Windows.
Functions
insecure-seed: func() -> tuple<u64, u64>since 0.2.0
Return a 128-bit value that may contain a pseudo-random value.
The returned value is not required to be computed from a CSPRNG, and may even be entirely deterministic. Host implementations are encouraged to provide pseudo-random values to any program exposed to attacker-controlled content, to enable DoS protection built into many languages' hash-map implementations.
This function is intended to only be called once, by a source language to initialize Denial Of Service (DoS) protection in its hash-map implementation.
Expected future evolution
This will likely be changed to a value import, to prevent it from being called multiple times and potentially used for purposes other than DoS protection.
