abstract suspend fun deleteKeySigningKey(input: DeleteKeySigningKeyRequest): DeleteKeySigningKeyResponse
Deletes a key-signing key (KSK). Before you can delete a KSK, you must deactivate it. The KSK must be deactivated before you can delete it regardless of whether the hosted zone is enabled for DNSSEC signing.
You can use DeactivateKeySigningKey to deactivate the key before you delete it.
Use GetDNSSEC to verify that the KSK is in an INACTIVE status.
