gst-crypto Overview
RidgeRun's gst-crypto plugin makes it easy to encrypt or decrypt content passing through a GStreamer pipeline. gst-crypto will take advantage of any available crypto hardware accelerators. gst-crypto is based on OpenSSL so any encryption technology supported by OpenSSL can be supported by gst-crypto. Currently, only aes-128-cbc cipher is support. gst-crypto source code has not yet been reviewed by experts for security deficiencies.
Also gst-crypto does not support seeking and some mux/demuxers, please inquire in case this is needed. RidgeRun has solutions that supports seeking while doing decrypting.
gst-crypto Features
- aes-128-cbc cipher support
- Password or key/iv setup
- GStreamer 0.10.x support
- GStreamer 1.x support
Example Use Cases
- Capture audio/video from a camera directly into an encrypted media file.
- Decrypt streaming audio/video and render to local display/speakers.
GStreamer Plugin Support
Please Contact RidgeRun for any modifications or extensions needed and Integration into other Embedded Linux Systems (e.g. Ubuntu, Yocto, ...).
Build and run on a local Linux PC
Tested on Ubuntu-14.04 64 bit:
Source code fetch
git clone git@github.com:RidgeRun/gst-crypto cd gst-crypto
GStreamer 0.10.x
git checkout release-0.10
GStreamer 1.x
git checkout release-1.0
Note: There are tagged releases also.
Compilation
./autogen.sh ./configure make sudo make install
If you don't want to install into your system you can specify directory path with:
GST_PLUGIN_PATH=src/.libs/ gst-launch ....
gst-crypto Source code
Location
RR SDK Integration
One of our demo SDK's can be used:
- i.MX6 SabreLite board - with crypto hardware acceleration
- DM368 Leopard board - no crypto hardware available
GStreamer 0.10.x
Note: v0.10.0 (gst-crypto-0.10.0.tar.gz) contains a bug that names the plugin gst-crypto instead of crypto. Please keep that in mind when running the test pipelines.

Example pipelines
Test pipeline
GStreamer 0.10.x
On RR SDK after regular installation to /usr/lib/gstreamer-0.10
echo "This is a crypto test ... " > plain.txt && gst-launch filesrc location=plain.txt ! crypto mode=enc ! crypto mode=dec ! filesink location=dec.txt && cat dec.txt
On Ubuntu after default installation to /usr/local/lib/gstreamer.0.10
echo "This is a crypto test ... " > plain.txt && gst-launch --gst-plugin-path=/usr/local/lib/gstreamer-0.10 filesrc location=plain.txt ! crypto mode=enc ! gst-crypto mode=dec ! filesink location=dec.txt && cat dec.txt

Using Crypto Hardware Acceleration
Crypto Hardware Acceleration can be used transparently with the plugin and can be configured independently.
There are some considerations to take into account:
- Does the MCU include a hardware crypto unit (e.g. CAAM on i.MX6)?
- Which setup would result in a performance gain (e.g data block size on i.MX6)?
- Is the cipher to be used supported by the hardware crypto unit and the kernel driver?
- Is the kernel driver implemented efficiently?
