Properties

$encryptionIV  : string

Encryption IV

$encryptionKey  : string

The encryption key.

$encryptionKeyFilename  : string

The encryption key filename.

$encryptionSecretsRoot  : mixed

Disk to store the secrets.

$listener  : StdListener

Listener that will rotate the key.

$nextEncryptionFilenameAndKey  : array<string|int, mixed>

A fresh filename and encryption key for the next round.

$onNewEncryptionKey  : callable

Gets called whenever a new encryption key is set.

$rotateEncryptiongKey  : bool

Wether to rotate the key on every segment.

$segmentsOpened  : int

Number of opened segments.

$segmentsPerKey  : int

Number of segments that can use the same key.

Methods

generateEncryptionKey()  : string

Creates a new encryption key.

generateEncryptionKeyFilename()  : string

Creates a new encryption key filename.

withEncryptionKey()  : HLSExporter|EncryptsHLSSegments

Initialises the disk, info and IV for encryption and sets the key.

withRotatingEncryptionKey()  : HLSExporter|EncryptsHLSSegments

Enables encryption with rotating keys. The callable will receive every new key and the integer sets the number of segments that can use the same key.

addHandlerToRotateEncryptionKey()  : void

Adds a listener and handler to rotate the key on every new HLS segment.

cleanupHLSEncryption()  : HLSExporter|EncryptsHLSSegments

Removes the encryption keys from the temporary disk.

getEncrypedHLSParameters()  : array<string|int, mixed>

Returns an array with the encryption parameters.

removeHandlerThatRotatesEncryptionKey()  : HLSExporter|EncryptsHLSSegments

Remove the listener at the end of the export to prevent duplicate event handlers.

replaceAbsolutePathsHLSEncryption()  : HLSExporter|EncryptsHLSSegments

While encoding, the encryption keys are saved to a temporary directory.

rotateEncryptionKey()  : string

Rotates the key and returns the absolute path to the info file. This method should be executed as fast as possible, or we might be too late for FFmpeg opening the next segment. That's why we don't use the Disk-class magic.
