Package-level declarations

DrmSecurityLevel is a sealed class that represents the security level of the DRM system. DRM supports three security levels: L1, L3, and AUTO. L1 is the highest level of security, where all decryption, content processing, and key handling are done within the device’s hardware-secured areas. L3 is the lowest security level in Widevine. It relies on software to perform decryption and security processing. AUTO is used to automatically select the drm security level based on hardware device.
