Techniques for utilizing time-based security criteria in a file security system are disclosed. At least a portion of the security criteria can have a time associated therewith (i.e., time-based security criteria) that serves as a time-based restriction on the ability to gain access to electronic files. If the time-based restriction is not satisfied, then the associated security criteria is not made available and thus access to a secured electronic file is prevented. In other words, access restrictions on electronic files can be dependent on the time at which access to the electronic files is attempted. The security criteria can pertain to keys (or ciphers) used by the file security system to secure (e.g., encrypt) electronic files to be secured, or to unsecure (e.g., decrypt) electronic files already secured.
