/**
 * 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 1.4 factory must always create 1.4 ICryptoPlugin interfaces, which are
 * returned via the 1.0 createPlugin method.
 *
 * To use 1.4 features the caller must cast the returned interface to a
 * 1.4 HAL, using V1_4::ICryptoPlugin::castFrom().
