Anyone know of a program that allows you to do this:
1. You send a zipped file to a friend but you password protect it first (a bit like winrar or winzip).
2. The password is generated based on a changing variable, eg a future date.
3. You give your friend the password for that date. ie it won't work before/after that date.
4. But you yourself can open it on any date by generating another password using step 2.
Is there any existing tool that anyone knows about like this either on Windows or Linux? Or maybe any of the existing array of zip or encryption tools under Linux?
Say you use a binary you encrypt with burneye, then how about letting a stub "phone home" to get the real time, and then download the files? Not that this would keep ppl from "inspecting" whatever calls are made, but there are ways to obfuscate it a bit. (/me looks in unordered $HOME/chaos for links/docs)

Rep:
hmm, just an idea, but has anyone thought of an encrytion algorithm that requires the file to be on a machine with a certian RSA fingerprint (as in the one used by the sshd for establishing secure remote access)? that i think would be more secure than a time stamp if only your computer or his can even open it, unless of course RSA fingerprints are user definable
