Gstreamer element for encryption

[Baby Octopus]

Hi,

I need to encrypt by stream before sending it to the client

gst-launch-1.0 videotestsrc ! x264enc bitrate=1000 ! mpegtsmux ! tcpserversink

Is it possible to insert an encryption element between the mpegtsmux and udpsink. Is htere any gstreamer element meant for encryption which is based on openssl or any other library?

There is none currently, but you could relatively easily write
something. I see two simple options here

1) Change tcpserversink (and possibly the other TCP elements) to use
GLib's TLS support. Then you can have full-blown TLS with certificate
checking, client-side authentication, etc..

2) Just write a small filter-like element that encrypts all data with
some kind of cipher, e.g. by using openssl. How secure that's going to
be depends on what you're doing there though :)
