Systems and methods are provided for data access protection. The disclosed computing system can determine a passphrase for controlling access to a file, operate a hash function on the passphrase by a predetermined number of iterations to provide an intermediate passphrase, and send a request for an enhanced passphrase to a server in communication with the apparatus, where the request can include the intermediate passphrase. Subsequently, the disclosed computing system can receive, from the server, the enhanced passphrase based on the intermediate passphrase in response to the request. |
