Corrected 2026-09-11, comments only. This patch still called Bouncy Castle
"audited" in three places after that adjective had already been removed from the
production sources and from the copies published beside it, because nothing
compared the patch with the sources it is generated from. We cannot cite an audit
of bcprov-jdk18on: it is not a FIPS validated module and we know of no published
third-party review of it. What is citable is byte-for-byte agreement with the NIST
KAT and ACVP vectors in both directions, and that is what the comments now say.
No code changed; the wording did.
