Hi all,

Sorry for cross-posting but thought it might reach the right people. I need to encrypt media streams before streaming them to any player. I found few links that talk about using WM-DRM for the purpose. I also found relevant headers(CONTENT ENCRYPTION OBJECT, EXTENDED CONTENT ENCRYPTION OBJECT, DIGITAL SIGNATURE OBJECT etc) in Asf specification that are probably used for this; however there are no details on what bytes would belong to these headers(like from index x1 to x2, these many bytes belong to private key, y1 to y2 belong to public key etc.). Please help.

Thanks in advance,
-DD
