fn verify_channel_v2(
req: &InjectionRequest,
shared_dir: &Path,
now_secs: i64,
) -> Option<bool>Expand description
Identity M4d-6: the v2 cross-channel signature against the keys published
for its source_uid (M4d-5). None when there is nothing to check (no
v2 sent, no key published for the UID); Some(false) when one was
published and the signature, or its freshness, fails.
