File Encryption Form is Submittable w/ Blank Password Fields

Expected Behavior

Submitting blank password fields when Encrypting a File results in an error, or the form cannot be submitted until entries exist in both fields.

Actual Behavior

Submitting blank password fields when Encrypting a File causes the dialog window to close without creating an encrypted file, and with no error message explaining what just happened.
