...neither IDEA nor triple-DES *can* encrypt with no "password" (by
which I have to assume you mean what is normally, for a block cipher,
called a "key").

Perhaps you mean "some non-secret key"[%], which is not the same thing
as *no* key.  (Of course, from a security point of view, if a
non-secret key is used, it makes no difference which one it is.)

[%] The one resulting from following the usual algorithms on a
    zero-length passphrase, perhaps...?
