How can I Encrypt Video in Real Time?

Question

I\'m looking for a, preferably open source, library or program to encrypt video in real time for security purposes, not DRM. I\'ve found several decent algorithms, RVEA and VEA,

Answer 1

I'd suggest used AES-128 in counted block (not the usual chained block) mode. It's easily done using openssl, and it's available in hardware on most all mobile and CE devices, so those become options should you had that way in the future.

One place it's used is in the chunked HTTP streaming from apple per this spec: http://tools.ietf.org/html/draft-pantos-http-live-streaming-02
