Remember, it is not necessary to give particularly good performance in
the case of a bad password.
Also, you are not decrypting unstructured binary data ... it's highly
structured stuff. First of all, does zlib give up when trying to
inflate? If not, AbiWord's XML parsing certainly will. All you
really have to do is trap the "I am punting" paths and turn them into
"I am punting, and it is probably because you used a bad password".
