I have put a prototype of an imp/exp for a password protected abw 
document for comments at
http://www.frydrych.uklinux.net/abi/eabw.gz
To get it work you will need to modify the makefile that controls the 
linkage to include libAbiCrypto.

The exporter is derived from the AbiWord_1 file format. The xml 
document is compressed using zlib deflate and then encrypted 
with blowfish in 8bit CFB mode.

The functions _getKey of the imp and exp are not for real; there are 
just hacks to allow testing without needing to design a gui for 
password entry, the password is typed into the console window.
