             Summary: Detect and indicate file encrypted with Rights Management Service RMS/IRM
                 Key: TIKA-3666
                 URL: https://issues.apache.org/jira/browse/TIKA-3666
             Project: Tika
          Issue Type: Improvement
          Components: metadata
            Reporter: August Valera


Rights Management Service (RMS), implemented in MS Office as Information Rights Management (IRM), allows organizations to set file permissions that are stored within the file. In most cases, this will result in the file getting a new extension (with a prefix p, such as {{.txt}} becoming {{{}.ptxt{}}}), but in the case of MS Office and PDF files, which support this natively, the implementation results in the file contents being encrypted without any extension change. 

Current behavior: Running such files through Tika produces results as if it was an empty file ran through {{DefaultParser}} and {{{}OfficeParser{}}}.

Expected behavior: Extract more metadata about necessary permissions to view (if possible), and throwing {{EncryptedDocumentException}} as is the case with Office files encrypted in the more traditional manner.
