PublicKeyAlgorithm Property

The algorithm of an asymmetric key pair.

Syntax

 googlekms.getPublicKeyAlgorithm([callback])

Default Value

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for the getPublicKeyAlgorithm([callback]) method is defined as:

function(err, data){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'data' is the value returned by the method.

The callback for the setPublicKeyAlgorithm([callback]) method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This property reflects the algorithm of an asymmetric key pair stored on the server; it is populated anytime the GetPublicKey method is called successfully. Possible values are:
