Has anyone had any luck getting encrypted streaming to work with Apple's HTTP Live Streaming using openssl? It seems I'm almost there but my video doesn't play but I don't get any errors in Safari either (like "Video is unplayable" or "You don't have permission to play this video" when I got the key wrong). 

#bash script:
keyFile="key.txt"
openssl rand 16 > $keyFile
hexKey=$(cat key.txt | hexdump -e '"%x"')
hexIV='0'
openssl aes-128-cbc -e -in $fileName -out $encryptedFileName -p -nosalt -iv ${hexIV}  -K ${hexKey}


#my playlist file:
#EXTM3U
#EXT-X-TARGETDURATION:000020
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-KEY:METHOD=AES-128,URI="key.txt"
#EXTINF:20, no desc
test.ts.enc
#EXT-X-ENDLIST

I was using these docs as a guide:

Okay, I figured it out... My hexdump command was wrong. It should be:

hexKey=$(cat key.txt | hexdump -e '16/1 "%02x"')
