20/**
21 * ICryptoFactory is the main entry point for interacting with a vendor's
22 * crypto HAL to create crypto plugins. Crypto plugins create crypto sessions
23 * which are used by a codec to decrypt protected video content.
24 *
25 * The 1.4 factory must always create 1.4 ICryptoPlugin interfaces, which are
26 * returned via the 1.0 createPlugin method.
27 *
28 * To use 1.4 features the caller must cast the returned interface to a
29 * 1.4 HAL, using V1_4::ICryptoPlugin::castFrom().
