SPac 將壓縮和加密結合到一個產品中，並利用使用者友好的介面使操作安全存檔變得簡單。 除了壓縮和加密之外，我們認為 SPac 還具有獨特的功能，可以簡單保護和共用敏感檔。任何 SPac 套件都可以轉換為具有差異的自提取存檔。與類似工具的 SPac 不同，您的包的收件者不需要自己的 SPac 副本。他們可以添加、刪除和修改包中的檔，以及簡單地提取它們。 通過使用 SPac，您的敏感文件永遠不需要永久存在於磁碟上，同時仍然允許受信任的朋友和關聯者修改它們。一旦使用者提供了所需的密碼，他們只需按兩下檔即可修改檔，然後將自動加密更改並儲存在存檔中，並將工作檔從磁碟擦除。 加密和發送任何類型的檔給同事通過電子郵件（或大多數其他基於檔的通信軟體），在知道只有收件者可以查看包的內容的安全。 SPac 是在美國境外開發和編譯的，沒有後門或代管鑰匙，不受美國出口限制。使用非常強的 BlowFish（448 位元金鑰）演演算法對檔進行加密，高壓縮可降低檔大小。
