I want to encrypt an IMPORTANT file and send it over the internet...but the problem is after the recipient views it I want it to self destruct or something like that for obvious security reasons. So my question is whether there is any software or method to encrypt a file and ADD some self-destruct code to it which will delete the file after a period of time...or even if there is only a way to just self-destruct the file?unless you wrap the data inside an executable....

maybe something like:
handle=shellexecute somedatfile.ext
if handle is closed then delete somedatfile.ext

but the data will still be in the mail server for example if you send it via email.

now, the problem is how to attach a file to the end of an executable??You could simply send a link to view the document which you retain on your P.C.

Then you CONTROL when the file is deleted or the link is cancelled.

There remains the "security hazard" that the other party can take a screen shot, just as they could if you sent a self-deleting file.

thanks for your responses...but it seems that it is pretty difficult to do what i wanted to do. so i THINK i would'nt want to risk sending this file anymore...ill find another way sooner or later. thanks once again!
