CryptoOperation object

Deprecated. A CryptoOperation object provides methods and events for initialization, processing data, and completing a cryptographic operation.

Warning As of Microsoft Edge, CryptoOperation has been replaced by a Promise object as the return value for cryptography operations. See Web Cryptography API updates for more info.

Inheritance Hierarchy

The CryptoOperation does not inherit from any class or interface.

Members

The CryptoOperation object has these types of members:

Events
Methods
Properties

Events

The CryptoOperation object has these events.

Event	Description
onabort	Deprecated. Fired when the current cryptographic operation (CryptoOperation) is aborted.
oncomplete	Deprecated.Fires when the current cryptographic operation completes.
onerror	Deprecated.Fires when the current cryptographic operation encounters an error.
onprogress	Deprecated.Fired periodically during the current cryptographic operation (CryptoOperation).

Methods

The CryptoOperation object has these methods.

Method	Description
abort	Deprecated. Aborts the current CryptoOperation.
addEventListener	Registers an event handler for the specified event type.
dispatchEvent	Sends an event to the current element.
finish	Deprecated. Requests that the current CryptoOperation be completed, with its result returned asynchronously.
process	Deprecated. Requests that the current CryptoOperation cryptographically process the given data.
removeEventListener	Removes an event handler that the addEventListener method registered.

Properties

The CryptoOperation object has these properties.

Property	Access type	Description
algorithm	Read-only	The KeyAlgorithm used to generate the cryptographic key.
key	Read-only	The Key object used to initialize the cryptographic operation (CryptoOperation).
result	Read-only	The result of the current cryptographic operation.

Remarks

A CryptoOperation object is returned from the encrypt, decrypt, sign, verify, and digest methods of the subtle property. A CryptoOperation object provides methods and events for dealing with initialization, processing data, and completing the cryptographic operation, yielding the final output.
