type nonrec t = {constantInitializationVector : string option;This is a 128-bit, 16-byte hex value represented by a 32-character text string. If this parameter is not set then the Initialization Vector will follow the segment number by default.
*)encryptionMethod : HlsEncryptionType.t option;Encrypts the segments with the given encryption scheme. Leave blank to disable. Selecting 'Disabled' in the web interface also disables encryption.
*)initializationVectorInManifest : HlsInitializationVectorInManifest.t option;The Initialization Vector is a 128-bit number used in conjunction with the key for encrypting blocks. If set to INCLUDE, Initialization Vector is listed in the manifest. Otherwise Initialization Vector is not in the manifest.
*)offlineEncrypted : HlsOfflineEncrypted.t option;Enable this setting to insert the EXT-X-SESSION-KEY element into the master playlist. This allows for offline Apple HLS FairPlay content protection.
*)spekeKeyProvider : SpekeKeyProvider.t option;If your output group type is HLS, DASH, or Microsoft Smooth, use these settings when doing DRM encryption with a SPEKE-compliant key provider. If your output group type is CMAF, use the SpekeKeyProviderCmaf settings instead.
*)staticKeyProvider : StaticKeyProvider.t option;Use these settings to set up encryption with a static key provider.
*)type_ : HlsKeyProviderType.t option;Specify whether your DRM encryption key is static or from a key provider that follows the SPEKE standard. For more information about SPEKE, see https://docs.aws.amazon.com/speke/latest/documentation/what-is-speke.html.
