If you intend to cipher the file only once, you can't do it at transport
level anyway (except for multicast, but that's probably NOT what you
want to use).
IMHO, the cleanest wayt to do it on the client side would be to add a
new access plugin that does the deciphering while piggybacking on
another access plugin to actually get the ciphered data (HTTP, file,
etc). This should be relatively easy, and VLC already depends on
libgcrypt for the TLS support, so all the common symmetric ciphers are
I bet provisioning personnal key pairs to clients will be a lot more
complicated, in the first place.
