我在 Macbook Air 上用 Textwrangler 编写的文本文件丢失了一些数据。我在扩展名为 .plist 的文件中找到了其中一些。文件是用 xml 编写的，如下所示:

如何解码“数据”标签内的数据？

最佳答案

数据中的代码是Base64 ，可以使用任何在线工具轻松解码，例如 this one .

PrintingFont 的数据将解码为一个二进制文件，其中包含的信息如果转换为 ASCII(显然不包括注释)，将或多或少看起来像这样:

// !!! BINARY PROPERTY LIST WARNING !!!
//
// The pretty-printed property list below has been created
// from a binary version on disk and should not be saved as
// the ASCII format is a subset of the binary representation!
//
{   "$archiver" = "NSKeyedArchiver";
    "$objects" = (
        "$null",
        {   "$class" = :false;
            NSFontDescriptorAttributes = :false;
        },
        {   "$class" = :false;
            NS.keys = ( :false, :false );
            NS.objects = ( :false, :false );
        },
        "NSFontNameAttribute",
        "NSFontSizeAttribute",
        "Menlo-Regular",
        12,
        {   "$classes" = ( "NSMutableDictionary", "NSDictionary", "NSObject" );
            "$classname" = "NSMutableDictionary";
        },
        {   "$classes" = ( "NSFontDescriptor", "NSObject" );
            "$classname" = "NSFontDescriptor";
        },
    );
    "$top" = { root = :false; };
    "$version" = 100000;
}

MD5 数据解码为 A62248B900DBD8D082B9A2E11FF80D2B，我认为这是一个 MD5 哈希。
