/**
 * ICryptoFactory is the main entry point for interacting with a vendor's
 * crypto HAL to create crypto plugins. Crypto plugins create crypto sessions
 * which are used by a codec to decrypt protected video content.
 *
 * The 1.2 factory must always create 1.2 ICryptoPlugin interfaces, which are
 * returned via the 1.0 createPlugin method.
 *
 * To use 1.2 features the caller must cast the returned interface to a
 * 1.2 HAL, using V1_2::IDrmPlugin::castFrom().
 *
 * The ICryptoFactory hal is required because all top-level interfaces
 * have to be updated in a minor uprev.
