 | 
						|
 * This file contains platform-dependent type definitions.
 | 
						|
 *
 | 
						|
 * In implementations with isolation between the application and the
 | 
						|
 * cryptography module, implementers should take care to ensure that
 | 
						|
 * the definitions that are exposed to applications match what the
 | 
						|
 * module implements.
