密钥对

更新时间：2024-07-02

创建密钥对

如下代码可以创建密钥对，单个用户在单region默认配额500个（创建和导入的密钥对之和）创建后的密钥对可植入实例以实现远程登录实例：

                Java
                
            

                import com.baidubce.BceClientConfiguration;
import com.baidubce.Protocol;
import com.baidubce.auth.DefaultBceCredentials;
import com.baidubce.services.bcc.BccClient;
import com.baidubce.services.bcc.BccClientConfiguration;
import com.baidubce.services.bcc.model.keypair.KeypairCreateRequest;
import com.baidubce.services.bcc.model.keypair.KeypairModel;

public class CreateKeypair {
    public static void main(String[] args) {
        // 设置您的ak、sk和要访问的endpoint
        String endpoint = "http://bcc.bj.baidubce.com";
        String ak = "ak";
        String sk = "sk";
        // 设置默认配置
        BceClientConfiguration bccClientConfiguration = new BccClientConfiguration()
                .withProtocol(Protocol.HTTP)
                .withCredentials(new DefaultBceCredentials(ak, sk))
                .withEndpoint(endpoint);
        // 创建bcc client
        BccClient client = new BccClient(bccClientConfiguration);

        String keyName = "dcc";
        String keyDes = "用于dcc";

        KeypairCreateRequest keypairCreateRequest = new KeypairCreateRequest();
        // 设置密钥名
        keypairCreateRequest.setName(keyName);
        // 设置密钥描述
        keypairCreateRequest.setDescription(keyDes);
        KeypairModel keypairModel = client.createKeypair(keypairCreateRequest);
        System.out.println(keypairModel.getPublicKey());
    }
}
            

导入密钥对

如下代码可以导入创建密钥对：

                Java
                
            

                import com.baidubce.BceClientConfiguration;
import com.baidubce.Protocol;
import com.baidubce.auth.DefaultBceCredentials;
import com.baidubce.services.bcc.BccClient;
import com.baidubce.services.bcc.BccClientConfiguration;
import com.baidubce.services.bcc.model.keypair.KeypairImportRequest;
import com.baidubce.services.bcc.model.keypair.KeypairModel;

public class ImportKeypair {
    public static void main(String[] args) {
        // 设置您的ak、sk和要访问的endpoint
        String endpoint = "http://bcc.bj.baidubce.com";
        String ak = "ak";
        String sk = "sk";
        // 设置默认配置
        BceClientConfiguration bccClientConfiguration = new BccClientConfiguration()
                .withProtocol(Protocol.HTTP)
                .withCredentials(new DefaultBceCredentials(ak, sk))
                .withEndpoint(endpoint);
        // 创建bcc client
        BccClient client = new BccClient(bccClientConfiguration);

        KeypairImportRequest requst = new KeypairImportRequest();
        // 创建密钥对名称
        requst.setName("keypairFromImport");   
        // 待创建的密钥对的描述,可选参数
        requst.setDescription("self desc...."); 
        // 待创建的密钥对的公钥
        requst.setPublicKey("ssh-***"); 
        KeypairModel keypairModel = client.importKeypair(requst);
        System.out.println(keypairModel.getPublicKey());
    }
}
            

查询密钥对列表

如下代码可以查询密钥对列表：

                Java
                
            

                import com.baidubce.BceClientConfiguration;
import com.baidubce.Protocol;
import com.baidubce.auth.DefaultBceCredentials;
import com.baidubce.services.bcc.BccClient;
import com.baidubce.services.bcc.BccClientConfiguration;
import com.baidubce.services.bcc.model.keypair.KeypairListRequest;
import com.baidubce.services.bcc.model.keypair.KeypairListResponse;

public class ListKeypair {
    public static void main(String[] args) {
        // 设置您的ak、sk和要访问的endpoint
        String endpoint = "http://bcc.bj.baidubce.com";
        String ak = "ak";
        String sk = "sk";
        // 设置默认配置
        BceClientConfiguration bccClientConfiguration = new BccClientConfiguration()
                .withProtocol(Protocol.HTTP)
                .withCredentials(new DefaultBceCredentials(ak, sk))
                .withEndpoint(endpoint);
        // 创建bcc client
        BccClient client = new BccClient(bccClientConfiguration);
        // 创建请求体
        KeypairListRequest keypairListRequest = new KeypairListRequest();
        // 每页包含的最大数量，最大数量通常不超过1000。缺省值为1000
        keypairListRequest.setMaxKeys(1);               
        // 批量获取列表的查询的起始位置，是一个由系统生成的字符串
        keypairListRequest.setMarker("k-gXZ7LlbS");     
        KeypairListResponse keypairListResponse = client.listKeypair(keypairListRequest);
        System.out.println(keypairListResponse.getKeypairs());
    }
}
            

查询密钥对详情

如下代码可以查询单个密钥对的详细信息：

                Java
                
            

                import com.baidubce.BceClientConfiguration;
import com.baidubce.Protocol;
import com.baidubce.auth.DefaultBceCredentials;
import com.baidubce.services.bcc.BccClient;
import com.baidubce.services.bcc.BccClientConfiguration;
import com.baidubce.services.bcc.model.keypair.KeypairDetailRequest;
import com.baidubce.services.bcc.model.keypair.KeypairModel;

public class KeypairDetail {
    public static void main(String[] args) {
        // 设置您的ak、sk和要访问的endpoint
        String endpoint = "http://bcc.bj.baidubce.com";
        String ak = "ak";
        String sk = "sk";
        // 设置默认配置
        BceClientConfiguration bccClientConfiguration = new BccClientConfiguration()
                .withProtocol(Protocol.HTTP)
                .withCredentials(new DefaultBceCredentials(ak, sk))
                .withEndpoint(endpoint);
        // 创建bcc client
        BccClient client = new BccClient(bccClientConfiguration);
        // 创建请求体
        KeypairDetailRequest keypairDetailRequest = new KeypairDetailRequest();
        // 设置被查询密钥对id
        keypairDetailRequest.setKeypairId("k-***");
        // 查询密钥对详情
        KeypairModel keypairModel = client.keypairDetail(keypairDetailRequest);
        System.out.println(keypairModel.getPublicKey());
    }
}
            

绑定密钥对

如下代码可以将所选密钥对（限单个）绑定到所选BCC实例（支持多台），目前一台BCC实例只能绑定一个密钥对：

                Java
                
            

                import com.baidubce.BceClientConfiguration;
import com.baidubce.Protocol;
import com.baidubce.auth.DefaultBceCredentials;
import com.baidubce.services.bcc.BccClient;
import com.baidubce.services.bcc.BccClientConfiguration;
import com.baidubce.services.bcc.model.keypair.KeypairAttachRequest;
import java.util.ArrayList;
import java.util.List;

public class AttachKeypair {
    public static void main(String[] args) {
        // 设置您的ak、sk和要访问的endpoint
        String endpoint = "http://bcc.bj.baidubce.com";
        String ak = "ak";
        String sk = "sk";
        // 设置默认配置
        BceClientConfiguration bccClientConfiguration = new BccClientConfiguration()
                .withProtocol(Protocol.HTTP)
                .withCredentials(new DefaultBceCredentials(ak, sk))
                .withEndpoint(endpoint);
        // 创建bcc client
        BccClient client = new BccClient(bccClientConfiguration);

        List<String> instances = new ArrayList<String>();
        // 设置被绑定实例id，可多个
        instances.add("i-***");            
        KeypairAttachRequest keypairAttachRequest = new KeypairAttachRequest();
        // 设置被绑定密钥对id
        keypairAttachRequest.setKeypairId("k-***");        
        keypairAttachRequest.setInstanceIds(instances);
        client.attachKeypair(keypairAttachRequest);
    }
}
            

解绑密钥对

如下实例可以将所选BCC实例与它们各自绑定的密钥对解绑，此操作仅适用于Linux系统的BCC实例，且所选BCC实例必须处于运行中或关机状态：

                Java
                
            

                import com.baidubce.BceClientConfiguration;
import com.baidubce.Protocol;
import com.baidubce.auth.DefaultBceCredentials;
import com.baidubce.services.bcc.BccClient;
import com.baidubce.services.bcc.BccClientConfiguration;
import com.baidubce.services.bcc.model.keypair.KeypairDetachRequest;

import java.util.ArrayList;
import java.util.List;

public class DetachKeypair {
    public static void main(String[] args) {
        // 设置您的ak、sk和要访问的endpoint
        String endpoint = "http://bcc.bj.baidubce.com";
        String ak = "ak";
        String sk = "sk";
        // 设置默认配置
        BceClientConfiguration bccClientConfiguration = new BccClientConfiguration()
                .withProtocol(Protocol.HTTP)
                .withCredentials(new DefaultBceCredentials(ak, sk))
                .withEndpoint(endpoint);
        // 创建bcc client
        BccClient client = new BccClient(bccClientConfiguration);
        // 创建请求体
        KeypairDetachRequest keypairDetachRequest = new KeypairDetachRequest();
        // 被绑密钥ID
        keypairDetachRequest.setKeypairId("k-***");
        List<String> a = new ArrayList<String>();
        a.add("i-***");
        a.add("i-***");
        // 实例
        keypairDetachRequest.setInstanceIds(a);
        // 发起解绑
        client.detachKeypair(keypairDetachRequest);
    }
}
            

删除密钥对

如下代码可以删除密钥对，已经绑定BCC实例的密钥对无法被删除：

                Java
                
            

                import com.baidubce.BceClientConfiguration;
import com.baidubce.Protocol;
import com.baidubce.auth.DefaultBceCredentials;
import com.baidubce.services.bcc.BccClient;
import com.baidubce.services.bcc.BccClientConfiguration;
import com.baidubce.services.bcc.model.keypair.KeypairDeleteRequest;

public class DeleteKeypair {
    public static void main(String[] args) {
        // 设置您的ak、sk和要访问的endpoint
        String endpoint = "http://bcc.bj.baidubce.com";
        String ak = "ak";
        String sk = "sk";
        // 设置默认配置
        BceClientConfiguration bccClientConfiguration = new BccClientConfiguration()
                .withProtocol(Protocol.HTTP)
                .withCredentials(new DefaultBceCredentials(ak, sk))
                .withEndpoint(endpoint);
        // 创建bcc client
        BccClient client = new BccClient(bccClientConfiguration);
        // 构建请求体
        KeypairDeleteRequest keypairDeleteRequest = new KeypairDeleteRequest();
        // 被删密钥ID
        keypairDeleteRequest.setKeypairId("k-***");
        // 发起删除请求
        client.deleteKeypair(keypairDeleteRequest);
    }
}
            

重命名密钥对

如下代码可以重命名密钥对：

                Java
                
            

                import com.baidubce.BceClientConfiguration;
import com.baidubce.Protocol;
import com.baidubce.auth.DefaultBceCredentials;
import com.baidubce.services.bcc.BccClient;
import com.baidubce.services.bcc.BccClientConfiguration;
import com.baidubce.services.bcc.model.keypair.KeypairRenameRequest;

public class RenameKeypair {
    public static void main(String[] args) {
        // 设置您的ak、sk和要访问的endpoint
        String endpoint = "http://bcc.bj.baidubce.com";
        String ak = "ak";
        String sk = "sk";
        // 设置默认配置
        BceClientConfiguration bccClientConfiguration = new BccClientConfiguration()
                .withProtocol(Protocol.HTTP)
                .withCredentials(new DefaultBceCredentials(ak, sk))
                .withEndpoint(endpoint);
        // 创建bcc client
        BccClient client = new BccClient(bccClientConfiguration);
        // 创建请求体
        KeypairRenameRequest keypairRenameRequest = new KeypairRenameRequest();
        // 待重命名的密钥对id
        keypairRenameRequest.setKeypairId("k-***");
        // 新的密钥对名称
        keypairRenameRequest.setName("Name2");
        // 发起更新秘钥对名称
        client.renameKeypair(keypairRenameRequest);
    }
}
            

更改密钥对描述

如下代码可以更改密钥对描述，若用户提供的新的描述内容为空，则删除密钥对之前的描述。

                Java
                
            

                import com.baidubce.BceClientConfiguration;
import com.baidubce.Protocol;
import com.baidubce.auth.DefaultBceCredentials;
import com.baidubce.services.bcc.BccClient;
import com.baidubce.services.bcc.BccClientConfiguration;
import com.baidubce.services.bcc.model.keypair.KeypairDetailRequest;
import com.baidubce.services.bcc.model.keypair.KeypairModel;
import com.baidubce.services.bcc.model.keypair.KeypairUpdateDescRequest;

public class UpdateKeypairDescription {
    public static void main(String[] args) {
        // 设置您的ak、sk和要访问的endpoint
        String endpoint = "http://bcc.bj.baidubce.com";
        String ak = "ak";
        String sk = "sk";
        // 设置默认配置
        BceClientConfiguration bccClientConfiguration = new BccClientConfiguration()
                .withProtocol(Protocol.HTTP)
                .withCredentials(new DefaultBceCredentials(ak, sk))
                .withEndpoint(endpoint);
        // 创建bcc client
        BccClient client = new BccClient(bccClientConfiguration);
        // 创建请求体
        KeypairUpdateDescRequest keypairUpdateDescRequest = new KeypairUpdateDescRequest();
        // 待更改描述的密钥对id
        keypairUpdateDescRequest.setKeypairId("k-***");
        // 新的密钥对描述
        keypairUpdateDescRequest.setDescription("desc");
        // 更新keypair的描述信息
        client.updateKeypairDescription(keypairUpdateDescRequest);
    }
}
