Hello,

I recently had the occasion to dive into the softraid crypto code [1]
and was quite pleased with the cleanliness of it all. However, I found
surprising the default value of 8k PBKDF2 rounds.

I know it is easy to override and I should have RTFM, but I (naively,
I'll admit) assumed OpenBSD would pick very robust defaults, erring on
the conservative side. Is it maybe time to bump it up, or pick it based
on a quick machine benchmark?

If there's consensus I might also provide a patch for the live benchmark
option.

Thank you
