Nick Burch commented on TIKA-3960:
----------------------------------

If possible, please include a small test file and update {{tika-parsers/src/test/java/org/apache/tika/mime/TestMimeTypes.java}} to test the detection

> We use Tika for detecting and validating uploaded files using their content/magic bytes and not only their names/extension.
> Passing a PGP/GPG encrypted file to Tika.detect(InputStream stream) will always return application/octet-stream instead of application/pgp-encrypted defined in tika-mimetypes.xml
> The issue occurs because the application/pgp-encrypted mime-type defined in tika-mimetypes.xml is lacking a magic match and only has <glob pattern="*.pgp"/>
> I managed to fix the issue for us temporarily by adding application/pgp-encrypted including a magic match in our custom-mimetypes.xml file. I will create a Pull Request on Github with the fix to resolve the issue.
