Blowfish encryption

I have an app that was written in VB6 then compiled to what appears to be native code then it was packed with a version of UPX (probally old version) the new versions of UPX will not un-pack, but I managed to un-pack the program with a PE Editor....

now after inspecting the headder I find the unpacked program has a Blowfish encryption signature ... since I do not know the original password I cannot de-crypt with Blowfish program.


the unpacked program runs fine just as it did before I un-packed it, so I am making head way ..

can anyone toss me a bone about Blowfish .. I have been to the author's site and studied the program and I think source is available for blowfish but not sure that will help.
