推荐答案

您可以使用密码对其进行加密.

You can encrypt it (with a password).

作为JSOP说，您可以加密文件的内容.使用密码创建DES3密钥或类似的内容(使用框架随附的一种加密算法)，对内容进行加密并重新保存文件.请注意，尽管如此，该文件实际上不再是文本文件，只能由您的应用程序读取.

文本格式中无法以类似于ZIP文件的方式指定密码，兼容的编辑器将可以提示您输入密码并打开文件.

As JSOP says, you can encrypt the contents of the file. Use the password to create a DES3 key or something similar (using one of the cryptographic algorithms shipped with the framework), encrypt the content and re-save the file. Note though that if you do this, the file is essentially no longer a text file and will only be readable by your application.

There is no capability within the text format to specify a password in a similar way to ZIP files, where compliant editors will be able to prompt for it and open the file.
