php - Working with encrypted files in Laravel (how to download decrypted file) -

in webapp, users can upload files. before being saved , stored, contents of file encrypted using this:

crypt::encrypt(file_get_contents($file->getrealpath())); 

i use file system comes laravel move file

storage::put($filepath, $encryptedfile); 

i have table store information each file columns such as:

• id
• file_path
• file_name
• original_name (includes extension)

now want user able download encrypted file. however, i'm having trouble decrypting file , returning user. in file downloads response section of laravel documentation, suggests this:

return response()->download($pathtofile, $name, $headers); 

it wants file path fine, @ point can decrypt file contents readable?

i seem able this:

$encryptedcontents = storage::get($filerecord->file_path); $decryptedcontents = crypt::decrypt($encryptedcontents); 

... don't know how return download specified file name.

you manually create response so:

$encryptedcontents = storage::get($filerecord->file_path); $decryptedcontents = crypt::decrypt($encryptedcontents);  return response()->make($decryptedcontents, 200, array(     'content-type' => (new finfo(fileinfo_mime))->buffer($decryptedcontents),     'content-disposition' => 'attachment; filename="' . pathinfo($filerecord->file_path, pathinfo_basename) . '"' )); 

you can check out laravel api more info on parameters of make method are. pathinfo function used extract filename path sends correct filename response.
