There's now a known attack for generating 2 strings that happen to hash
to the same MD5 hash value fairly easily.

The more general problem of generating a second string that hashes to
an already known/fixed MD5 hash is still basically infeasible (unless you're
a very well funded spook agency *and* know something the rest of us don't)...
