我正在尝试使用amazon aws进行加密和解密.我有例外
Exception in thread "main" com.amazonaws.AmazonClientException: Unable to build cipher: Illegal key size

当我试图将对象用于使用AmazonS3EncryptionClient进行加密时,我得到了异常.如何解决此错误.
AmazonS3EncryptionClient s3 = new AmazonS3EncryptionClient(credentials,materialProvider); …堆栈跟踪
Exception in thread "main" com.amazonaws.services.s3.model.AmazonS3Exception: Forbidden (Service: Amazon S3; Status Code: 403; Error Code: 403 Forbidden; Request ID: null), S3 Extended Request ID: null

当我将对象存储在 AmazonS3EncryptionClient 对象中时，出现此异常。这是我的代码
ObjectMetadata objectMetadata = new ObjectMetadata();
objectMetadata.setContentLength(plaintext.length);
objectMetadata.setSSEAlgorithm(ObjectMetadata.AES_256_SERVER_SIDE_ENCRYPTION);
AmazonS3EncryptionClient s3 = new AmazonS3EncryptionClient(credentials,materialProvider).withRegion(Region.getRegion(Regions.US_EAST_1));;
PutObjectRequest putRequest = new PutObjectRequest(
bucket, keyId, new ByteArrayInputStream(plaintext), objectMetadata);
putRequest.setRequestCredentials(credentials);
s3.setEndpoint("https://kms.us-east-1.amazonaws.com");
