• CloudHsmClusterNotActiveException:

  The request was rejected because the AWS CloudHSM cluster that is associated with the custom key store is not active. Initialize and activate the cluster and try the command again. For detailed instructions, see Getting Started in the AWS CloudHSM User Guide.

• CustomKeyStoreInvalidStateException:

  The request was rejected because of the ConnectionState of the custom key store. To get the ConnectionState of a custom key store, use the DescribeCustomKeyStores operation.

  This exception is thrown under the following conditions:

  • You requested the CreateKey or GenerateRandom operation in a custom key store that is not connected. These operations are valid only when the custom key store ConnectionState is CONNECTED.

  • You requested the UpdateCustomKeyStore or DeleteCustomKeyStore operation on a custom key store that is not disconnected. This operation is valid only when the custom key store ConnectionState is DISCONNECTED.

  • You requested the ConnectCustomKeyStore operation on a custom key store with a ConnectionState of DISCONNECTING or FAILED. This operation is valid for all other ConnectionState values.

• CustomKeyStoreNotFoundException:

  The request was rejected because AWS KMS cannot find a custom key store with the specified key store name or ID.

• KMSInternalException:

  The request was rejected because an internal exception occurred. The request can be retried.

• CloudHsmClusterInvalidConfigurationException:

  The request was rejected because the associated AWS CloudHSM cluster did not meet the configuration requirements for a custom key store.

  • The cluster must be configured with private subnets in at least two different Availability Zones in the Region.

  • The security group for the cluster (cloudhsm-cluster-<cluster-id>-sg) must include inbound rules and outbound rules that allow TCP traffic on ports 2223-2225. The Source in the inbound rules and the Destination in the outbound rules must match the security group ID. These rules are set by default when you create the cluster. Do not delete or change them. To get information about a particular security group, use the DescribeSecurityGroups operation.

  • The cluster must contain at least as many HSMs as the operation requires. To add HSMs, use the AWS CloudHSM CreateHsm operation.

    For the CreateCustomKeyStore, UpdateCustomKeyStore, and CreateKey operations, the AWS CloudHSM cluster must have at least two active HSMs, each in a different Availability Zone. For the ConnectCustomKeyStore operation, the AWS CloudHSM must contain at least one active HSM.

  From the ImportKeyMaterial operation, the request was rejected because AWS KMS could not decrypt the encrypted (wrapped) key material.

• KeyUnavailableException:

  The request was rejected because the specified CMK was not available. You can retry the request.

• InvalidKeyUsageException:

  The request was rejected for one of the following reasons:

  • The KeyUsage value of the CMK is incompatible with the API operation.

  • The encryption algorithm or signing algorithm specified for the operation is incompatible with the type of key material in the CMK (CustomerMasterKeySpec).

  For encrypting, decrypting, re-encrypting, and generating data keys, the KeyUsage must be ENCRYPT_DECRYPT. For signing and verifying, the KeyUsage must be SIGN_VERIFY. To find the KeyUsage of a CMK, use the DescribeKey operation.

  To find the encryption or signing algorithms supported for a particular CMK, use the DescribeKey operation.

    'KeyId' => 'alias/ExampleAlias', // The identifier of the CMK to use to encrypt the data key. You can use the key ID or Amazon Resource Name (ARN) of the CMK, or the name or ARN of an alias that refers to the CMK.
    'KeySpec' => 'AES_256', // Specifies the type of data key to return.
]);

Result syntax:

[
    'CiphertextBlob' => <BLOB>, // The encrypted data key.
    'KeyId' => 'arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab', // The ARN of the CMK that was used to encrypt the data key.
]

GenerateRandom

$result = $client->generateRandom([/* ... */]);
$promise = $client->generateRandomAsync([/* ... */]);

Parameter Syntax

$result = $client->generateRandom([
    'CustomKeyStoreId' => '<string>',
    'NumberOfBytes' => <integer>,
]);
