             Summary: Detector return "application/x-x509-key" when scanning a .p12 file
                 Key: TIKA-3784
                 URL: https://issues.apache.org/jira/browse/TIKA-3784
             Project: Tika
          Issue Type: Bug
          Components: detector
    Affects Versions: 1.26
            Reporter: Matthias Hofbauer


We are using tika to check if the MIME type of the file extensions matches with the MIME type of the file content.

After our upgrade from tika-core 1.22 to 1.26 our logic does not work anymore for certificates of type .p12, .pfx, .cer, .der.

For the .p12 and .pfx extension the MIME type is "application/x-pkcs12" but the tika detector returns "application/x-x509-key" instead.

After checking the tika-mimetype.xml and comparing it to my .p12 file I found the following MIME magic which explains why I got these types back.
{code:xml}
<mime-type type="application/x-x509-key;format=der">
    <sub-class-of type="application/x-x509-key"/>
    <!-- These are just a bunch of magic integers as defined by the key format... -->
    <!-- Always seem to have a version integer as their first entry, -->
    <!--  normally 00, 01 or 02, check for that -->
    <magic priority="40">
      <match value="0x3081FF020100" type="string"
              mask="0xFFFF00FFFFFC" offset="0"/>
      <match value="0x3082FFFF020100" type="string"
              mask="0xFFFF0000FFFFFC" offset="0"/>
    </magic>
</mime-type> {code}
