文件签名说的就是二进制的文件头或文件尾，，是用来表示文件类型的。

比如 JPG文件的二进制开头是 FF D8 FF ，这就是它的文件签名。修改了这个会导致文件打不开，实现隐藏的目的。
所以文件签名修复，就是推测文件头，并修复其二进制信息，使得其还原成其本来的类型，能用对应的工具打开。

这是一个文件签名列表，用于识别或验证文件内容的数据。此类签名也称为幻数或魔术字节。

许多文件格式不打算作为文本阅读。如果这样的文件不小心被视为文本文件，其内容将难以理解。但是，有时文件签名在解释为文本时可以被识别。ISO 8859-1列显示了文件签名在解释为常见ISO 8859-1编码中的文本时的显示方式，不可打印字符表示为控制代码缩写或符号，或可用的代码页 1252 字符，或其他框。在某些情况下，为了清楚起见，空格字符显示为 ␠。
