Steganos Privacy Suite is a Windows data-protection application from Steganos. It uses virtual data safes to store files in encrypted form, preventing their contents from being read without the required access credentials.
A .sef file contains data encrypted by Steganos and belongs to the associated virtual safe or encrypted archive. It is not intended to be edited as an ordinary document or archive.
Open a .sef file with Steganos Privacy Suite on Microsoft Windows. Use the software's data-safe functions and provide the required password or other credentials to access its contents.
A .sef file cannot normally be converted directly to another file format. Open it in Steganos Privacy Suite, decrypt or extract the required contents, and save those files in their original formats.
