Sure.  It's open source; you can use any algorithm you can code.  I
have patches to add an MD5-based hash, for example.  (I did them long
before the main NetBSD sources got MD5-based hashing.)

I would guess that the major difference is that OpenBSD hypes it more,
but as I don't follow NetBSD very closely these days and have never
followed OpenBSD, all I have in this regard is guesses.

In principle, yes: it would be relatively easy to build an encrypting
disk layer that encrypted blocks before writing them to disk,
decrypting on read, and then use that for swap.

Out of the box, probably not, though I'll let someone who knows
-current better than I answer more authoritatively.
