Could you rephrase your request in more clear way?

If you want to know which VCS beside Git use cryptographic hash function over commit info and commit parentage as commit id, then both Monotone (from which Git borrowed this idea) and Mercurial use it.

Bazaar, if I understand it correctly, and from what I remember, uses some UUID which includes commit digest as a commit identifier, but I don't know if Bazaar have immutable history.

In Subversion you can change svn:log (or something like that) property, i.e. change commit message, after the fact; I don't think there is any check for that. CVS doesn't support changesets, so it is out of question.

I don't know about Darcs, or BitKeeper, or ClearCase, or Perforce.
