Myrmec is a library that used to identifie real file format type by detecting the file binary head with out file extention.

This is a very small library, with only one function, which is to convert the file suffix name to the corresponding MIME type, and if you want to identify the real format of the file, you can refer to the myrmec project.

this is a asp.net core middleware that used to authorize the requests for the "non-public" files.
