Summary: 
This document specifies a new mechanism that completely encrypts header extensions and CSRCs for RTP. 

Major issues: None

Minor issues: None

Nits/editorial comments:

a couple of questions: 
- Section 4: this document defines a new "a=cryptex" Session Description Protocol (SDP) [RFC4566] attribute to indicate support. 
Then the next sentence states that "This attribute takes no value".  Why "no value"?  The first statement already says a new "a=cryptex" attribute.  It is confusing. 

-  Section 6.3:  what does "region" mean in the statement?   "The decryption procedure is identical to that of [RFC3711] except for the region to decrypt"  Do you mean the "header" to be encrypted by the scheme described in this document? 

Thank you, 
Linda Dunbar
