安全

安全分享文件:加密、密码和最佳实践

保护敏感文件在分享之前。涵盖加密、密码保护存档、安全转移方法以及避免常见错误。

通过电子邮件或云存储分享无需保护的文件就像寄信一样,任何窃取其中的人都可以读取内容。对于敏感文件、财务记录或个人照片,加密至关重要。

最简单的方法是密码保护的 ZIP 档案,使用 AES-256 密码加密。即使文件被窃取,内容也无法读取,ConvertCraft 的 Archive 工具将 ZIP 文件完全在浏览器中创建,文件永远不会离开你的设备。

对于单个 PDF 文档,你可以添加开放密码(需要查看)和权限密码(需要编辑或打印)。PDF 密码使用 AES-128 或 AES-256 依据工具,提供合同和财务报告等方面的强保护。

当分享加密文件时,不要通过文件发送密码。如果发送加密 ZIP,通过单独的渠道分享密码,例如短信、电话或像 Signal 这样的安全消息应用程序。

常见的错误包括使用弱密码(至少 12 个字符,包含混合大小写、数字和符号),通过公共链接分享,并且忘记在分享之前从文档中删除元数据。
