    • + *
  • Protection against certificate spoofing attacks

This manager provides automatic validation of SNS message signatures received via HTTP/HTTPS endpoints, + * ensuring that messages originate from Amazon SNS and have not been modified during transmission. + * It supports both SignatureVersion1 (SHA1) and SignatureVersion2 (SHA256) as per AWS SNS standards. + * + *

+ *     logger.error("SNS message validation failed: {}", e.getMessage());
+ * }
+ * }
+ *
+ * + *

Advanced usage with custom HTTP client: + * 

+ * {@code
+ * SnsMessageManager messageManager = SnsMessageManager.builder()

This class handles secure retrieval and caching of SNS signing certificates from AWS. - * It implements comprehensive security validations to ensure certificate authenticity and - * prevent various attack vectors including certificate spoofing and man-in-the-middle attacks. - * - *

Security Features: - *

    - *
  • HTTPS-only certificate retrieval to prevent interception attacks
    • - *
  • Certificate URL validation against known SNS-signed domains
    • - *
  • Support for different AWS partitions (aws, aws-gov, aws-cn)
    • - *
  • Thread-safe certificate caching with configurable TTL
    • - *
  • Protection against certificate spoofing attacks
    • - *
  • Certificate size validation to prevent resource exhaustion
    • - *
- * - *

Trusted Domains: - * The retriever only accepts certificates from pre-validated SNS domains including: - *

    - *
  • Standard AWS regions: {@code sns.*.amazonaws.com}
    • - *
  • AWS GovCloud: {@code sns.*.amazonaws.com}

This class coordinates between the message parser, signature validator, and certificate retriever - * to provide complete SNS message validation functionality. It handles the entire validation pipeline - * including JSON parsing, certificate retrieval and caching, and cryptographic signature verification. - * - *

The implementation supports: - *

    - *
  • Both SignatureVersion1 (SHA1) and SignatureVersion2 (SHA256) signature algorithms
    • - *
  • Automatic certificate retrieval and caching from trusted SNS domains
    • - *
  • All SNS message types (Notification, SubscriptionConfirmation, UnsubscribeConfirmation)
    • - *
  • Configurable HTTP client and certificate cache timeout settings
    • - *
  • Thread-safe concurrent usage
    • - *
- * - *

This class manages the lifecycle of HTTP resources and implements {@link SdkAutoCloseable} - * to ensure proper cleanup. When using a custom HTTP client via configuration, the client's - * lifecycle is managed externally. When using the default HTTP client, this class manages - * the client's lifecycle and closes it when {@link #close()} is called. - * - *

Thread Safety: This class is thread-safe and can be used concurrently - * from multiple threads. Certificate caching is implemented using thread-safe collections. - * - *

Resource Management: Instances should be closed when no longer needed - * to free HTTP client resources.

This feature was available in Java SDK v1 but is currently missing in v2, creating a gap for developers who need to verify the authenticity and integrity of SNS messages received via HTTP/HTTPS endpoints. The feature ensures that messages sent to customer HTTP endpoints are genuinely from Amazon SNS and have not been tampered with during transmission. - -This feature addresses the community request tracked in [GitHub Issue #1302](https://github.com/aws/aws-sdk-java-v2/issues/1302) and implements the signature verification process documented in the [AWS SNS Developer Guide](https://docs.aws.amazon.com/sns/latest/dg/sns-verify-signature-of-message.html). - -## Requirements - -### Requirement 1 - -**User Story:** As a Java developer using AWS SDK v2 with HTTP/HTTPS endpoints, I want to validate SNS message signatures automatically, so that I can ensure the authenticity and integrity of messages sent to my HTTP endpoints from SNS. - -#### Acceptance Criteria - -1.

WHEN the message signature is valid THEN the system SHALL return a parsed SNS message object with all message attributes -3. WHEN the message signature is invalid THEN the system SHALL throw a clear exception indicating signature validation failure -4. WHEN the message format is malformed OR contains unexpected fields THEN the system SHALL reject the message with an appropriate parsing exception -5.

WHEN retrieving signing certificates THEN the system SHALL use HTTPS only to prevent unauthorized interception attacks -2. WHEN validating certificates THEN the system SHALL verify that certificates are issued by Amazon SNS and have a valid chain of trust -3. WHEN processing certificate URLs THEN the system SHALL validate that URLs come from SNS-signed domains and reject untrusted sources -4. WHEN a message contains an invalid or unknown certificate URL THEN the system SHALL reject the message with a security exception -5. WHEN validating messages from different AWS partitions THEN the system SHALL use the appropriate partition-specific certificate endpoints -6. WHEN processing certificates THEN the system SHALL never trust certificates provided directly in messages without proper validation - -### Requirement 3 - -**User Story:** As a developer migrating from AWS SDK v1 to v2, I want the same core functionalities as the v1 SnsMessageManager, so that I can achieve equivalent SNS message validation capabilities in v2. - -#### Acceptance Criteria - -1. WHEN parsing SNS messages THEN the system SHALL provide message signature validation equivalent to v1 functionality -2. WHEN accessing parsed message content THEN the system SHALL provide access to all standard SNS message fields (Type, MessageId, TopicArn, Subject, Message, Timestamp, etc.) -3.
