decrypt file using rc4(repost)

I have a file encrypted in RC4 using a password that is 16 ascii characters (all ascii usable characters, even unreadable ones). The password was generated using the rand() along with time() during a certain time window: 1239350400 (start time in unix time) 1239352600 (end time in unix time) I need to find the correct password to decrypt the message, you will have to modify the code to be able to read from a file. ## Deliverables Here is the source code and cipher file.
