Examples with KMSEncryptionMaterialsProvider com.qcloud.cos.internal.crypto.KMSEncryptionMaterialsProvider used on opensource projects

Example 1 with KMSEncryptionMaterialsProvider

use of com.qcloud.cos.internal.crypto.KMSEncryptionMaterialsProvider in project cos-java-sdk-v5 by tencentyun.

the class AbstractCOSClientTest method initEncryptionClient.

protected static void initEncryptionClient() {
    COSCredentials cred = new BasicCOSCredentials(secretId, secretKey);
    clientConfig = new ClientConfig(new Region(region));
    if (generalApiEndpoint != null && generalApiEndpoint.trim().length() > 0 && serviceApiEndpoint != null && serviceApiEndpoint.trim().length() > 0) {
        UserSpecifiedEndpointBuilder userSpecifiedEndpointBuilder = new UserSpecifiedEndpointBuilder(generalApiEndpoint, serviceApiEndpoint);
        clientConfig.setEndpointBuilder(userSpecifiedEndpointBuilder);
    }
    EncryptionMaterialsProvider encryptionMaterialsProvider;
    if (encryptionMaterials instanceof KMSEncryptionMaterials) {
        KMSEncryptionMaterials kmsEncryptionMaterials = new KMSEncryptionMaterials(cmk);
        encryptionMaterialsProvider = new KMSEncryptionMaterialsProvider(kmsEncryptionMaterials);
    } else {
        encryptionMaterialsProvider = new StaticEncryptionMaterialsProvider(encryptionMaterials);
    }
    cosclient = new COSEncryptionClient(qcloudkms, new COSStaticCredentialsProvider(cred), encryptionMaterialsProvider, clientConfig, cryptoConfiguration);
}

Example 2 with KMSEncryptionMaterialsProvider

use of com.qcloud.cos.internal.crypto.KMSEncryptionMaterialsProvider in project cos-java-sdk-v5 by tencentyun.

the class KMSEncryptionClientDemo method createCosClient.

static COSClient createCosClient(String region) {
    // 初始化用户身份信息(secretId, secretKey)
    COSCredentials cred = new BasicCOSCredentials("AKIDxxxxxxxxxxxxxxxxxxxxxxxxxxxxx", "yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy");
    // 设置bucket的区域, COS地域的简称请参照 https://www.qcloud.com/document/product/436/6224
    ClientConfig clientConfig = new ClientConfig(new Region(region));
    // 为防止请求头部被篡改导致的数据无法解密，强烈建议只使用 https 协议发起请求
    clientConfig.setHttpProtocol(HttpProtocol.https);
    // 初始化 KMS 加密材料
    KMSEncryptionMaterials encryptionMaterials = new KMSEncryptionMaterials(cmk);
    // 使用AES/CTR模式，并将加密信息存储在文件元信息中.
    // 如果想要此次加密的对象被 COS 其他的 SDK 解密下载，则必须选择 AesCtrEncryption 模式
    CryptoConfiguration cryptoConf = new CryptoConfiguration(CryptoMode.AesCtrEncryption).withStorageMode(CryptoStorageMode.ObjectMetadata);
    // // 如果 kms 服务的 region 与 cos 的 region 不一致，则在加密信息里指定 kms 服务的 region
    // cryptoConf.setKmsRegion(kmsRegion);
    // // 如果需要可以为 KMS 服务的 cmk 设置对应的描述信息。
    // encryptionMaterials.addDescription("kms-region", "guangzhou");
    // 生成加密客户端EncryptionClient, COSEncryptionClient是COSClient的子类, 所有COSClient支持的接口他都支持。
    // EncryptionClient覆盖了COSClient上传下载逻辑，操作内部会执行加密操作，其他操作执行逻辑和COSClient一致
    COSEncryptionClient cosEncryptionClient = new COSEncryptionClient(new COSStaticCredentialsProvider(cred), new KMSEncryptionMaterialsProvider(encryptionMaterials), clientConfig, cryptoConf);
    return cosEncryptionClient;
