Hls Encryption

Hls encryption is to use the AES-128 bit to encrypt each ts file, the player in obtaining PlayList file, will according to the # EXT-X-KEY tag inside the request to obtain the decryption URL, and then request to decrypt the key, the obtained ts file will be decrypted with the key. Users can perform cookie verification on the URL of the key and other methods to authenticate the user. Example: PlayList file (copy the link to view the file content or play it directly with the vlc player)

Parameter description:

• hlsKeyBase64_urlsafe encoding or encrypted key
• hlsKeyUrlSpecifies the url of the key, which is base64_urlsafe encoded. This is used to generate m3u8 PlayList.
• hlsKeyTypeSpecifies the method for transferring the key.
  
  
  • If this parameter is not specified or 0 is specified, it is transmitted only in base64_urlsafe encoding mode.
  • Specified as 1.x( 1.0, 1.1 ,...), The encryption method of rsa oa ep is used to transmit the key by encoding. x indicates the version of the key.
  • Public Key: 1.0

To encrypt the slice, you only need to modify$fopsValue, suchavthumb/m3u8/segtime/10/hlsKey/ /hlsKeyType/ /hlsKeyUrl/

1. The plaintext is 16 bytes. Use the Public Key provided by qiniu and the following command to encrypt the plaintext:

$ echo -n [AES128KEY] | openssl rsautl -encrypt -oaep -inkey [QINIU_PUB_KEY_FILE] -pubin | openssl base64 -A | tr "+/" "-_"

1. If The value is the base64 encoding of the plaintext key. The value is 0. If The value is the ciphertext encrypted by the qiniu public key. The value can be 1.0 characters.

2. Fill in the plaintext address of the key, which is generally the address of your business server, and control the access permission to this url through the Business server process.
