File TypeRights-Managed HTML Document
What is an RMH file?
An RMH file is a rights-managed .HTML document created by the Rights-Managed HTML SDK. It contains MIME encapsulation of Aggregate HTML Documents (MHTML) content. RMH files are used to secure content so that only the intended recipient can view or print the MHTML content in the original format using Internet Explorer with the Rights Management add-on installed.
The MHTML content in RMH files is encrypted with Windows Rights Management (RM) using the RM client software development kit (SDK) and may be compressed with the zlib compression method.
