encrypted_volume_support.hpp

1. Overview

The encrypted_volume_support.hpp file detects encrypted containers, exports their metadata and coordinates optional unlock sessions.

This is an interface and data-contract file. It declares the public and internal types used by this subsystem, allowing implementation files and callers to share a stable compile-time contract.

Its paired source or interface file is encrypted_volume_support.cpp.

Primary responsibilities:

  • Recognize supported encrypted volume formats
  • Export metadata needed for specialist recovery
  • Create and clean temporary mapper or loop devices
  • Expose unlocked sources to the normal recovery pipeline

2. File Identity and Scope

  • Source path: src/encrypted_volume_support.hpp
  • Language: C++
  • File role: interface and data-contract file
  • Physical lines: 25
  • Non-empty lines: 20
  • SHA-256: 920f61c05db9de5741e58f74cd7239164a67c1fb8e81850e645b4a3fef0cbda7

The declarations in this file use the global namespace.

3. Dependencies

3.1 Project Headers

  • disk_reader.hpp
  • models.hpp

3.2 Standard and External Headers

  • string
  • vector

These dependencies define the file’s compile-time integration with the recovery engine, GTK interface, on-disk format decoders, operating-system services, or C++ standard library.

4. Declared Types

  • struct EncryptedContainerInfo.
  • class EncryptedVolumeSupport.

5. Constants and Configuration Values

No preprocessor or compile-time constants were detected as top-level declarations in this file.

6. Data Members and Persistent State

The interface declares the following state-bearing members:

  • std::string scheme
  • uint64_t offset_bytes {0}
  • uint64_t size_bytes {0}
  • uint64_t payload_offset_bytes {0}
  • std::string detail

These members hold configuration, parser context, UI widgets, source references, progress state, recovered metadata, or temporary resources according to the owning type.

7. API and Function Inventory

The following callable interfaces or definitions were detected:

  • static std::vector<ScanResult> probe(DiskReader&reader,const std::vector<ScanResult>&seed_results,std::vector<std::string>&logs) – Inspects the source and reports matching candidates or detected metadata.
  • static bool collect_detected_containers(const ScanReport&report,std::vector<EncryptedContainerInfo>&out) – Implements the operation identified by this API and updates or returns the associated state.

8. Operational Flow

The subsystem represented by this file normally participates in the following flow:

  1. Recognize supported encrypted volume formats.
  2. Export metadata needed for specialist recovery.
  3. Create and clean temporary mapper or loop devices.
  4. Expose unlocked sources to the normal recovery pipeline.
  5. Expose or execute the detected APIs: probe, collect_detected_containers.
  6. Return explicit results, progress data, recovered records, or diagnostics to the calling layer.

9. Validation and Error Handling

  • Byte offsets, sizes and lengths must be validated before arithmetic and before every read to avoid overflow and out-of-bounds access.

10. Runtime, Concurrency, and Resource Management

  • Deterministic behavior: callers depend on explicit return values and stable data structures to distinguish successful recovery from partial or invalid results.

11. Security and Data-Recovery Considerations

  • Recovery code should prefer read-only source access and avoid writing to the original damaged medium.
  • Raw devices and image files are treated as untrusted binary input; every offset and length must remain bounded by the source size.

12. Implementation Considerations

  • Changes to public declarations can affect every translation unit that includes this header and should preserve binary and source compatibility where required.
  • State-bearing members should have explicit ownership and initialization semantics, especially for references, pointers, file descriptors and GTK widgets.
  • Large-device arithmetic uses 64-bit values; additions and multiplications should be checked before use as offsets or allocation sizes.

13. Integration with the Recovery Pipeline

  • The file belongs to the source-discovery, parsing or support layer.
  • Its results feed scanner, recovery or reporting modules through shared models.
  • The API should remain deterministic so higher layers can combine results safely.

14. Licensing and Provenance

No explicit copyright or software-license statement was detected in the opening section of this individual file. Distribution terms should therefore be verified against the project-level license and repository metadata.

The SHA-256 value in this document can be used to associate the generated documentation with the exact source version analyzed.
