web api instance property
WorkerGlobalScope: crypto property
Available in workers
The crypto read-only property of the WorkerGlobalScope interface returns the Crypto object for this worker. This object gives workers access to certain cryptographic related services.
Although the property itself is read-only, all of its methods (and the methods of its
child object, SubtleCrypto) are not read-only, and therefore vulnerable
to attack by polyfill.
Although crypto is available on all workers, the returned Crypto object only has one usable feature in insecure contexts: the getRandomValues() method. In general, you should use this API only in secure contexts.
Value
An instance of the Crypto interface, providing access to general-purpose cryptography and a strong random-number generator.
Examples
See the example on the page for crypto, which uses the crypto property to access the getRandomValues() method.
