SPac 将压缩和加密结合到一个产品中，并利用用户友好的界面使操作安全存档变得简单。 除了压缩和加密之外，我们认为 SPac 还具有独特的功能，可以简单保护和共享敏感文件。任何 SPac 包都可以转换为具有差异的自提取存档。与类似工具的 SPac 不同，您的包的收件人不需要自己的 SPac 副本。他们可以添加、删除和修改包中的文件，以及简单地提取它们。 通过使用 SPac，您的敏感文件永远不需要永久存在于磁盘上，同时仍然允许受信任的朋友和关联者修改它们。一旦用户提供了所需的密码，他们只需双击文件即可修改文件，然后将自动加密更改并存储在存档中，并将工作文件从磁盘擦除。 加密和发送任何类型的文件给同事通过电子邮件（或大多数其他基于文件的通信软件），在知道只有收件人可以查看包的内容的安全。 SPac 是在美国境外开发和编译的，没有后门或代管钥匙，不受美国出口限制。使用非常强的 BlowFish（448 位密钥）算法对文件进行加密，高压缩可降低文件大小。
