Question How can i hide a process OR encrypt and then decrypt a string?


Hello,
I've got a problem where at the moment i pass data from one file to another with this method:-
script1:
...
commands
...
...
/script2 DATA
exit

script2:
...
...
$1
commands
...

Which gets the data back again, this is fine but the data being passed is sensitive data so i'd like to be able to either hide the process from a 'ps or top or whatever' OR pass the data so if it was viewed its encrypted, and all done pass wordless so it needs to be symmetrical encryption, using keys or something, obviously the data is being processed quite fast so the keys won't be around very long even though this still leads to possible data decryption, perhaps ow thinking about it both methods working together would be ok. Although as long as someone doesn't have root then the key should be safe and therefore the encrypted data safe. Basically thats what i do and i need to come up with something to hide the data.

Thanks

For renaming the process (which is security by obscurity and isn't recommended) you can take a look at the $0 variable -- in perl that is functionally the "process name" variable.
