# Steganography Infrastructure Module
The `steganography` module applies cryptographic hash manifests, text overlays, and interactive metadata objects (like `mailto` QR barcodes) directly to PDF post-rendering.
## Core Processor (`core.py`)
The primary orchestrator of steganography operations. It handles config extraction, hashing, alpha-text watermarking, and barcodes.
```python
from infrastructure.steganography import SteganographyConfig, SteganographyProcessor
from pathlib import Path
processor = SteganographyProcessor(SteganographyConfig(enabled=True, overlay_mode="text"))
final_pdf = processor.process(
Path("output.pdf"),
author_emails=["test@example.com"],
)
```
## Barcodes (`barcodes.py`)
Responsible for generating dense Error-Correction Q-Level QR codes and Code128 barcode strips.
```python
from infrastructure.steganography.barcodes import create_barcode_strip_overlay
overlay_pdf_bytes = create_barcode_strip_overlay(
page_width=612, page_height=792,
code128_data="paper-id-001",
)
```
## Setup & Hashing (`hashing.py`)
Provides deterministic SHA-256 and SHA-512 manifest exports alongside standard PDF payloads.
```python
from infrastructure.steganography.hashing import compute_file_hashes, write_hash_manifest
hashes = compute_file_hashes(Path("file.pdf"))
write_hash_manifest(Path("file.pdf"), hashes)
```
## Overlays (`overlays.py`)
For applying visual steganographic traits like diagonally rendered strings across every page.
```python
from infrastructure.steganography.overlays import create_watermark_overlay
overlay_bytes = create_watermark_overlay(page_width=612, page_height=792, text="CONFIDENTIAL", opacity=0.08)
```
