• CloudHsmClusterNotActiveException:

  The request was rejected because the 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 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 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 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 CloudHSM CreateHsm operation.

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

  From the Decrypt or ReEncrypt operation, the request was rejected because the specified ciphertext, or additional authenticated data incorporated into the ciphertext, such as the encryption context, is corrupted, missing, or otherwise invalid.

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

• KeyUnavailableException:

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

• IncorrectKeyException:

  The request was rejected because the specified KMS key cannot decrypt the data. The KeyId in a Decrypt request and the SourceKeyId in a ReEncrypt request must identify the same KMS key that was used to encrypt the ciphertext.

• InvalidKeyUsageException:

  The request was rejected for one of the following reasons:

  • The KeyUsage value of the KMS key 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 KMS key (KeySpec).

  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 KMS key, use the DescribeKey operation.

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

  • The KeyUsage value of the KMS key 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 KMS key (KeySpec).

  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 KMS key, use the DescribeKey operation.

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

• InvalidGrantTokenException:

  The request was rejected because the specified grant token is not valid.

• KMSInternalException:

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

• KMSInvalidStateException:

  The request was rejected because the state of the specified resource is not valid for this request.

  For more information about how key state affects the use of a KMS key, see Key state: Effect on your KMS key in the Key Management Service Developer Guide .
