. Xor v0.60 .
. ........... .
. .
. Una vez que se ejecuta queda residente en memoria, e intercepta la int .
. 21h (Dos) y 2fh (Multiplex int). .
. Ya instalado el programa, los files encriptados se pueden leer/escribir .
. normalmente, y sin que uno se de cuenta en disco son grabados encriptados. .
. Adem�s, si esta la opci�n Prompt del xor activada (xor /p1) cada vez .
. que sea creado un file, aparecer� en pantalla la pregunta de si desea .
. crear el archivo como encriptado.. (y=si) .
. La opci�n Prompt se desinstala con xor /p0. .
. .
. (�) El m�todo de encripci�n es, realmente, muy trucho, pero, tengase en .
. cuenta que esto esta en vias de desarrollo, y para hacer algo interesante .
. que funcione, conviene empezarlo de a poco! .
