How did you encode the value in step 6? Assuming that you can't enter arbitrary binary data into that password field, you could at most have used base64 which would probably be good (~20 characters, 64 possible characters). OTOH, you said "hex value". If you encoded your number as hex, you would get a 32 character long password (good if the target form allows for such LNG passwords), but only 16 possible characters which is way too little and defeats the purpose of all your elaborate setup
