It will take me a while to reverse it (if at all), but I think I got the encryption right: | Code: | while (offset < length)
eax <- eax << 4 + byte ptr [str+offset]
eax <- eax ^ ((eax & F0000000) >> 18)
inc offset
endw
eax <- eax & 0FFFFFFF |
EDIT: I'm gonna start having fun with it, I found the weak-spot 
As for a working password - 963150000003: | Code: | ;ASSUMED NUMERIC PASSWORD - MINIMUM
;RESULT < PRE-XOR < PRE-ADDITION | VALUE
;00FA57B3 < 80FA5733 < 80FA57B3 | 33

As you can see, the xor you used made my method possible
I wonder what the original password was though...(I only know that it was one word, and possibly ended with an s, c, 3 or # [by looking at an ascii table] )

FYI, The last letter IS 's'. First is 'N'.

You guys are crazy. How did you reverse engineer that? It's got me stumped.
I think I like memory editing better...
