Hi folks,

The Challenge

Anyone know of a good way of encrypting a file to an insecure server and
then when downloaded, it is also decrypted ? A strong password istead of
encryption is also possible.
Trying to make the process easy as many users and many files makes for a
time consuming task.

Scenario

We have many small but sensitive files, and insecure file server that is
backed up and on a network to thousands of users, backup et all.

Ideally, we would be able to upload the file onto the server with one
password between a small number of us, who can download it and decrypt it
simultaneously.

Thanks...

Karma
