[ParthNema13]

Please describe.
Enhances user experience by confirming to the user which file was selected for encryption.

Helps prevent accidental uploads or confusion when working with multiple files.

Proposed Solution
A element below the file input to display the selected file's name.

A JavaScript event listener that updates this span with the uploaded file’s name whenever the file input changes.
