I was able to find this in a quick google search:  
Simple support for fragment MP4 files isn’t the only thing new with HLS. It now also supports DRM-protected fMP4 segments using MPEG-CENC (Common Encryption). It is supported by all the major browsers, and MPEG-DASH already supports DRM protected Fmp4 files.
