# 使用 CloudHSM CLI 共享和取消共享密钥
<a name="manage-keys-cloudhsm-cli-share"></a>

使用本主题中的命令在 [CloudHSM CLI](cloudhsm_cli.md) 中共享和取消共享密钥。在中 AWS CloudHSM，创建密钥的加密用户 (CU) 拥有该密钥。所有者可以使用**key share**和**key unshare**命令与其他 CUs人共享和取消共享密钥。密钥的共享用户可在加密操作中使用密钥，但无法导出或删除密钥，也无法与其他用户共享密钥。

要共享密钥，您必须以拥有该密钥的加密用户（CU）的身份登录到 HSM。

## 示例：共享和取消共享密钥
<a name="w2aac15c21c11b9"></a>

**Example**  
以下示例演示了如何与加密用户（CU）`alice` 共享密钥和与其取消共享。除 **key share** 和 **key unshare** 命令外，共享和取消共享命令还需要使用 [CloudHSM CLI 密钥筛选器](manage-keys-cloudhsm-cli-filtering.md)的特定密钥以及要与之共享或取消共享密钥的用户的特定用户名。  

1. 首先，使用筛选器运行 **key list** 命令以返回特定的密钥，然后查看密钥已与谁共享。

   ```

1. 查看 `shared-users` 输出以确定当前与谁共享密钥。

1. 要与加密用户（CU）`alice` 共享此密钥，请输入以下命令：

   ```
   aws-cloudhsm > key share --filter attr.label="rsa_key_to_share" attr.class=private-key --username alice --role crypto-user
   {
     "error_code": 0,
     "data": {
       "message": "Key shared successfully"
     }
   }
   ```

   请注意，除了 **key share** 命令外，此命令还使用密钥的唯一标签和将与之共享密钥的用户的姓名。

1. 再次运行 **key list** 命令以确认已与 `alice` 共享该密钥：

   ```
   aws-cloudhsm > key list --filter attr.label="rsa_key_to_share" --verbose
   {
     "error_code": 0,
     "data": {
       "matched_keys": [

   ```

1. 要取消与 `alice` 共享同一密钥，请运行以下 **unshare** 命令：

   ```
   aws-cloudhsm > key unshare --filter attr.label="rsa_key_to_share" attr.class=private-key --username alice --role crypto-user
   {
     "error_code": 0,
     "data": {
       "message": "Key unshared successfully"
     }
   }
   ```

   请注意，除了 **key unshare** 命令外，此命令还使用密钥的唯一标签和将与之共享密钥的用户的姓名。

1. 再次运行 **key list** 命令并确认已取消与加密用户 `alice` 共享该密钥：

   ```
   aws-cloudhsm > key list --filter attr.label="rsa_key_to_share" --verbose
   {
     "error_code": 0,
