EncryptionConfig

Details required to encrypt a stream.

Field	Type	Label	Description
encryption_keys	EncryptionKey	repeated	List of encryption keys and associated information.

EncryptionKey

A single encryption key and associated information.

Field	Type	Label	Description
key_id	string		Unique identifier for the key, as identified by your DRM provider, represented as 32 hexadecimal digits in UUID 8-4-4-4-12 format (for example, d569cb35-bd05-48c7-a99d-92feb381df13) or plain 32 hexadecimal digits (for example, d569cb35bd0548c7a99d92feb381df13).
key_uri	string		URI of the key. This URI is inserted into the M3U8 header.
key	string		128-bit encryption key represented as 32 hexadecimal digits (for example, `f828863735a2d93fd538f4b8e9b8bd80`).
iv	string		128-bit encryption IV represented as 32 hexadecimal digits (for example, `217719cae3ffc905b62a248956c9321f`).
matchers	EncryptionKeyMatcher	repeated	A list of rules indicating which muxStream(s) in your channel should use this key. A muxStream will use the first matching key it finds. If this field is omitted, all muxStreams will treat the key as a match.

EncryptionKeyMatcher

A single rule indicating which muxStream(s) in your channel should use the key.

Field	Type	Label	Description
mux_streams	string	repeated	A list of muxStream IDs which should use the key.

Scalar Value Types

.proto Type	Notes	C++	Java	Python	Go	C#	PHP	Ruby
double		double	double	float	float64	double	float	Float
float		float	float	float	float32	float	float	Float
int32	Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint32 instead.	int32	int	int	int32	int	integer	Bignum or Fixnum (as required)
int64	Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint64 instead.	int64	long	int/long	int64	long	integer/string	Bignum
uint32	Uses variable-length encoding.	uint32	int	int/long	uint32	uint	integer	Bignum or Fixnum (as required)
uint64	Uses variable-length encoding.	uint64	long	int/long	uint64	ulong	integer/string	Bignum or Fixnum (as required)
sint32	Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int32s.	int32	int	int	int32	int	integer	Bignum or Fixnum (as required)
sint64	Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int64s.	int64	long	int/long	int64	long	integer/string	Bignum
fixed32	Always four bytes. More efficient than uint32 if values are often greater than 2^28.	uint32	int	int	uint32	uint	integer	Bignum or Fixnum (as required)
fixed64	Always eight bytes. More efficient than uint64 if values are often greater than 2^56.	uint64	long	int/long	uint64	ulong	integer/string	Bignum
sfixed32	Always four bytes.	int32	int	int	int32	int	integer	Bignum or Fixnum (as required)
sfixed64	Always eight bytes.	int64	long	int/long	int64	long	integer/string	Bignum
bool		bool	boolean	boolean	bool	bool	boolean	TrueClass/FalseClass
string	A string must always contain UTF-8 encoded or 7-bit ASCII text.	string	String	str/unicode	string	string	string	String (UTF-8)
bytes	May contain any arbitrary sequence of bytes.	string	ByteString	str	[]byte	ByteString	string	String (ASCII-8BIT)
