Narrative:

I was the first officer and pilot monitoring on this flight. We were 10 miles in trail of a B777 when we experienced a wake encounter. The plane rolled to the right about 45 degrees with the autopilot automatically disengaging. The captain rolled the aircraft back to wings level and climbed to 10;300 ft to escape the wake. I immediately notified ATC of the required change in altitude and the controller vectored us to be offset from the 777's wake. I immediately checked with the flight attendants. No one was injured and I explained briefly what had occurred to the customers. The rest of the flight was conducted in accordance with the flight manual and applicable fars.
