word 97 decryption has now been fully implemented.
contains a utility that can decrypt word97 docs given the
development version 0.5.29 and above of wv at
(or in abiword cvs) has this ability built in for conversion of
word docs to other formats.
The missing link that was eluding me was pointed out by
Dmitry Sumin <sumin at domain lostpassword.com> and simultaneously
found and implemented by Dieter Spaar <spaar at domain mirider.augusta.de>,
full kudos to him.
In short the index number of each page of ciphertext (each 0x200 unit)
modifies the data that is passed into the rc4 key preparation.
