FAQ
After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.
Example:
Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.

Some PHP packages are not free to download and because of that hosted in private repositories.
In this case some credentials are needed to access such packages.
Please use the auth.json textarea to insert credentials, if a package is coming from a private repository.
You can look here for more information.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Informations about the package nexus-audit
Nexus\Audit
Cryptographically-verified, immutable audit engine for compliance and forensic analysis
Overview
The Nexus\Audit package provides an enterprise-grade, immutable audit trail with cryptographic hash chains and optional digital signatures. This package is the compliance engine designed for high-integrity, legally-defensible audit logging where tampering detection and state verification are critical.
Key Features
✅ Cryptographic Hash Chains - Each audit record links to the previous via SHA-256 hashes
✅ Optional Digital Signatures - Ed25519 signatures for non-repudiation
✅ Per-Tenant Isolation - Separate hash chains and sequences per tenant
✅ Dual-Mode Logging - Synchronous for critical events, async for high-volume
✅ Tamper Detection - Automatic verification on retrieval
✅ Sequence Integrity - Gap detection and monotonic ordering
✅ Framework-Agnostic - Pure PHP 8.3+ with zero Laravel dependencies
✅ Compliance-Ready - Meets SEC-AUD-0486, SEC-AUD-0490 requirements
Core Differences from AuditLogger
| Feature | Nexus\Audit (Engine) | Nexus\AuditLogger (Utility) |
|---|---|---|
| Purpose | Immutable, verifiable audit trail | User-friendly search/export/timeline |
| Immutability | Cryptographic hash chain enforcement | Append-only by convention |
| Data Storage | Raw, unmasked data for forensics | Masked data for display |
| Write Mode | Sync (critical) + Async (bulk) | Primarily async |
| Verification | Hash chain + signature verification | None |
| Use Case | Compliance, legal, security events | Activity feeds, debugging, reporting |
