https://github.com/NixOS/nixpkgs/blob/master/pkgs/stdenv/generic/setup.sh#L948
this can do it nicely.

+      The program tries to decrypt at least one of the key slots by trying
+      all the possible passwords. It is especially useful if you know
+      something about the password (i.e. you forgot a part of your password but
+      still remember most of it). Finding the password of a volume without
+      knowing anything about it would take way too much time (unless the
+      password is really short and/or weak). It can also use a dictionary.
