Initial implementation: Haskell PHP hardening tool
Complete implementation including: - PHP parser using Megaparsec (full PHP 8.x syntax support) - Complete AST representation - Security analysis (SQLi, XSS, CSRF, command injection, path traversal) - WordPress-specific constraints and hook analysis - Taint tracking for data flow analysis - Type inference engine - Code transformations (strict_types, type hints, sanitization) - PHP code emitter - Multi-format reporting (JSON, SARIF, HTML) - Infrastructure export (php.ini, nginx, Guix) - Guix container integration for WordPress CLI commands: analyze, fix, report, export 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Haskell-based PHP hardening and security analysis tool.
8+
9+
== Overview
10+
11+
Sanctify-PHP transforms PHP code to be safer and more robust:
12+
13+
* Adds `declare(strict_types=1)` declarations
14+
* Infers and adds type hints
15+
* Detects security vulnerabilities (SQLi, XSS, CSRF, command injection)
16+
* Enforces WordPress-specific constraints
17+
* Performs taint tracking analysis
18+
* Generates reports in JSON/SARIF/HTML formats
19+
* Exports infrastructure recommendations (php.ini, nginx, Guix)
20+
21+
== Installation
22+
23+
[source,bash]
24+
----
25+
# Using Cabal
26+
cabal build
27+
cabal install
28+
29+
# Using Nix
30+
nix build
31+
32+
# Using Guix
33+
guix build -f guix.scm
34+
----
35+
36+
== Usage
37+
38+
[source,bash]
39+
----
40+
# Analyze files
41+
sanctify analyze ./wp-content/plugins/my-plugin/
42+
43+
# Auto-fix safe issues
44+
sanctify fix ./src/
45+
46+
# Generate report
47+
sanctify report ./theme/ > report.json
48+
49+
# Export infrastructure config
50+
sanctify export --php-ini ./project/ >> php.ini
51+
sanctify export --nginx ./project/ >> security.conf
52+
sanctify export --guix ./project/ >> overrides.scm
53+
----
54+
55+
== Transformation Categories
56+
57+
=== Fully Automatic (Zero Risk)
58+
59+
* Add `declare(strict_types=1)`
60+
* Add ABSPATH check for WordPress files
61+
* Add missing text domains to i18n functions
62+
* Wrap echo with `esc_html()` for variables
63+
* Add `exit;` after `wp_redirect()`
64+
* Convert `rand()` → `random_int()`
65+
66+
=== Semi-Automatic (Review Recommended)
67+
68+
* Wrap superglobals with sanitizers
69+
* Replace `$wpdb->query()` with `$wpdb->prepare()`
70+
* Infer return types from function body
71+
* Add nonce verification to form handlers
72+
73+
=== Advisory Only
74+
75+
* SQL injection in complex queries
76+
* Hardcoded secrets detection
77+
* CSRF in AJAX handlers
78+
* Capability escalation patterns
79+
80+
== Container Integration
81+
82+
Sanctify-PHP integrates with the `aegis` container orchestrator to provide infrastructure-level hardening. See `guix/wordpress-container.scm` for an example hardened WordPress container.
83+
84+
[source,bash]
85+
----
86+
# Generate container config based on analysis
87+
sanctify export --guix ./project/ | aegis apply
88+
----
89+
90+
