要使用Amazon Secrets Manager和Java 7来访问密钥并使用CipherSuites加密/解密数据，可以按照以下步骤进行操作：

1. 添加所需的依赖项：在您的Java项目的构建文件（例如pom.xml）中添加以下依赖项：

    
        software.amazon.awssdk
        secretsmanager
        2.17.90
    

2. 导入所需的类：在您的Java类中导入所需的类：

import software.amazon.awssdk.auth.credentials.DefaultCredentialsProvider;
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.secretsmanager.SecretsManagerClient;
import software.amazon.awssdk.services.secretsmanager.model.GetSecretValueRequest;
import software.amazon.awssdk.services.secretsmanager.model.GetSecretValueResponse;
import software.amazon.awssdk.services.secretsmanager.model.SecretsManagerException;
import software.amazon.awssdk.services.secretsmanager.model.InvalidRequestException;
import software.amazon.awssdk.services.secretsmanager.model.DecryptionFailureException;
import software.amazon.awssdk.services.secretsmanager.model.InternalServiceErrorException;
import software.amazon.awssdk.services.secretsmanager.model.ResourceNotFoundException;
import software.amazon.awssdk.services.secretsmanager.model.UnauthorizedOperationException;

3. 创建Amazon Secrets Manager客户端：使用以下代码创建Amazon Secrets Manager客户端：

Region region = Region.US_EAST_1; // 替换为您的区域
SecretsManagerClient secretsManagerClient = SecretsManagerClient.builder()
    .region(region)
    .credentialsProvider(DefaultCredentialsProvider.create())
    .build();

4. 获取密钥值：使用以下代码获取密钥值：

String secretName = "your-secret-name"; // 替换为您的密钥名称
GetSecretValueRequest getSecretValueRequest = GetSecretValueRequest.builder()
    .secretId(secretName)
    .build();

GetSecretValueResponse getSecretValueResponse;
try {
    getSecretValueResponse = secretsManagerClient.getSecretValue(getSecretValueRequest);
} catch (InvalidRequestException | DecryptionFailureException | InternalServiceErrorException | 
        ResourceNotFoundException | UnauthorizedOperationException e) {
    // 处理异常
    e.printStackTrace();
    return;
}

String secretValue = getSecretValueResponse.secretString();

5. 使用CipherSuites进行加密/解密：使用以下代码示例使用CipherSuites进行加密/解密：

import javax.crypto.Cipher;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;
import java.nio.charset.StandardCharsets;
import java.util.Base64;

public class CipherExample {
    private static final String ALGORITHM = "AES/CBC/PKCS5PADDING";
    private static final String KEY = "your-secret-key"; // 替换为您的密钥

    public static String encrypt(String value) throws Exception {
        Cipher cipher = Cipher.getInstance(ALGORITHM);
        SecretKeySpec keySpec = new SecretKeySpec(KEY.getBytes(StandardCharsets.UTF_8), "AES");
        IvParameterSpec ivSpec = new IvParameterSpec(KEY.getBytes(StandardCharsets.UTF_8));
        cipher.init(Cipher.ENCRYPT_MODE, keySpec, ivSpec);
        byte[] encryptedBytes = cipher.doFinal(value.getBytes());
        return Base64.getEncoder().encodeToString(encryptedBytes);
    }

    public static String decrypt(String encryptedValue) throws Exception {
        Cipher cipher = Cipher.getInstance(ALGORITHM);
        SecretKeySpec keySpec = new SecretKeySpec(KEY.getBytes(StandardCharsets.UTF_8), "AES");
        IvParameterSpec ivSpec = new IvParameterSpec(KEY.getBytes(StandardCharsets.UTF_8));
        cipher.init(Cipher.DECRYPT_MODE, keySpec, ivSpec);
        byte[] decryptedBytes = cipher.doFinal(Base64.getDecoder().decode(encryptedValue));
        return new String(decryptedBytes);
    }

    public static void main(String[] args) {
        try {
            String encryptedValue = encrypt("Hello, World!");
            System.out.println("Encrypted value: " + encryptedValue);

            String decryptedValue = decrypt(encryptedValue);
            System.out.println("Decrypted value: " + decryptedValue);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

请注意，上述代码示例仅用于演示目的，实际应用中需要更复杂的安全性和错误处理机制。您还需要根据您的实
