KeyKeySpec Property

The key spec of the CMK.

Syntax

 amazonkms.getKeyKeySpec(index, [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 getKeyKeySpec([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 setKeyKeySpec([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

The key spec of the CMK.

This property reflects the key spec of the CMK. For symmetric CMKs, the only possible value is SYMMETRIC_DEFAULT which, according to the Amazon KMS documentation, is based on AES-256-GCM. For asymmetric CMKs, possible values are:

  • RSA_2048
  • RSA_3072
  • RSA_4096
  • ECC_NIST_P256 (secp256r1)
  • ECC_NIST_P384 (secp384r1)
  • ECC_NIST_P521 (secp521r1)
  • ECC_SECG_P256K1 (secp256k1)

The size of the array is controlled by the KeyCount property.

This property is read-only and not available at design time.
