Hi@akhtar,
AWS Key Management Service (KMS) makes it easy for you to create and manage cryptographic keys and control their use across a wide range of AWS services and in your applications. You can create a custom key store that is associated with an AWS CloudHSM cluster that you own and manage. The following create-custom-key-store example creates a custom key store with an existing custom key store.
$ aws kms create-custom-key-store --custom-key-store-name ExampleKeyStore --cloud-hsm-cluster-id cluster-1a23b4cdefg --key-store-password kmsPswd --trust-anchor-certificate file://customerCA.crt
