Supported Formats

KeyView support for Azure RMS files depends on the encryption method that Azure RMS uses for each file type, and on whether the file is classified or protected. In Azure RMS, classified files have additional labels to inform users of their sensitivity, while protected files are encrypted so that only authorized users can view them.

In some cases, KeyView format detection returns a different file type depending on whether the file is classified or protected.

The following sections provide information about the Azure RMS support for different file types, and metadata support.

For more information about XrML extraction, see the subFileType member of the KVSubFileInfo structure.

Microsoft Office Files

The following table describes KeyView detected formats for Microsoft Office files that Azure RMS encrypts by creating an OLE container.

For these files:

• KeyView can get classification metadata.
• KeyView can detect whether the file is Azure RMS encrypted (the kWindowsRMSEncrypted flag).

• When you configure credentials through fpConfigureRMS, Filter and File Extraction API functions can operate on the protected data of the file (see fpConfigureRMS()). In this case, you can filter, extract, and get summary information.

In most cases, KeyView can also extract the XrML file for these files when they are protected, and identify the XrML files as KVSubFileType_XrML.

Implemented as pFile

The following table describes the KeyView detected formats for files that Azure RMS encrypts by creating a pFile around the document.

For these files:

• KeyView can get classification metadata.

• KeyView can detect whether the file is Azure RMS encrypted (the kWindowsRMSEncrypted flag).

• KeyView can extract the XrML if the file is protected.

• When you configure credentials through fpConfigureRMS, Filter and File Extraction API functions can operate on the protected data of the file (see fpConfigureRMS()). In this case, you can filter, extract, and get summary information.

PDF Files

The following table describes the KeyView detected formats for PDF documents, which Azure RMS encrypts by creating an encrypted PDF (in which each stream and metadata value is encrypted), wrapped in a container PDF. KeyView allows you to extract the encrypted PDF from the container, and then for the extracted file:

• KeyView can detect whether the file is Azure RMS encrypted (the kWindowsRMSEncrypted flag).

• KeyView can extract the XrML if the file is protected.

• When you configure credentials through fpConfigureRMS, Filter and File Extraction API functions can operate on the protected data of the file (see fpConfigureRMS()). In this case you can filter, extract, and get summary information for PDF formats.

Restricted Permission Messages

Azure RMS encrypts email messages by creating an encrypted rpmsg attachment, which contains the original message body and attachments, attached to an unencrypted container message, which contains the message metadata. KeyView can extract the metadata and the encrypted rpmsg from the container message, and then for the extracted rpmsg:

• KeyView can detect that the file is Azure RMS encrypted (the kWindowsRMSEncrypted flag).
• When you configure credentials through fpConfigureRMS, File Extraction API functions can operate on the protected data of the file (see fpConfigureRMS()). This allows you to extract the message body and attached files, but attached messages are not currently supported.
