If you think it's necessary, I would like to add the test inside the
static <clinit> block of AbstractDrbg$SeederHolder. The test will be
on Hash_DRBG/SHA-256 and whatever mech/algorithm defined by
securerandom.drbg.config (They are the same by default). The test will
be in the same thread (otherwise I don't know how to report an error).
If it fails, a RuntimeException will be thrown.
Please read over this section, but I *THINK* you are supposed to run a
known-answer test on each SecureRandom instance created, not just the
single one used as a seeder during <clinit>:
Known-answer tests shall be conducted on each DRBG function within
a boundary or sub-boundary prior to the first use of that DRBG
(e.g., during the power-on self-testing sequence).
Which may mean that you'll need a known-answer test for each
configuration type. Unless I'm interpreting this wrong.
I have not read the spec, but this sounds like something when FIPS is
enabled, not during normal operation. Are you sure a POST is required
during normal usage?
