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.

Kodhe Encrypt - Modernized CI3 Encrypt Library
Library enkripsi modern untuk CodeIgniter 3 dengan dukungan OpenSSL, menggantikan library mcrypt yang sudah deprecated.
⚠️ DEPRECATED NOTICE
Library ini DEPRECATED dan dipertahankan hanya untuk backward compatibility. Untuk proyek baru, gunakan library Encryption resmi CodeIgniter 3 yang berbasis OpenSSL.
🚀 Fitur Utama
- ✅ OpenSSL Support: AES-256-CBC + HMAC-SHA256 untuk keamanan maksimal
- ✅ Backward Compatible: API sama persis dengan CI3 Encrypt lama
- ✅ Legacy Data Support: Bisa membaca data enkripsi lama (mcrypt)
- ✅ Tamper Proof: Deteksi otomatis jika data di-tamper
- ✅ PSR-4 Compliant: Struktur modular dan modern
- ✅ Performance Optimized: Caching key derivation, batch operations
- ✅ Migration Path: Method
migrate()untuk migrasi data lama ke format baru
📦 Instalasi
Atau tambahkan ke composer.json:
🔧 Konfigurasi
Tambahkan di application/config/config.php:
PENTING: Gunakan key minimal 32 karakter untuk keamanan optimal!
💡 Cara Penggunaan
Gaya CI3 Tradisional
Gaya Modern PSR-4
🔐 Keamanan
Format Data Baru (OpenSSL)
- IV (Initialization Vector): Random setiap enkripsi
- HMAC: Mencegah tampering/data manipulation
- AES-256-CBC: Standard industri untuk enkripsi simetris
Deteksi Tampering
🔄 Migrasi dari Legacy (mcrypt)
Library ini otomatis mendeteksi dan membaca data legacy CI3:

🧪 Testing
📊 Perbandingan dengan CI3 Asli
| Fitur | CI3 Encrypt (mcrypt) | Kodhe Encrypt (OpenSSL) |
|---|---|---|
| Engine | Mcrypt ❌ (removed PHP 7.2+) | OpenSSL ✅ |
| Integritas | ❌ Tidak ada | ✅ HMAC-SHA256 |
| Tamper Proof | ❌ Silent corruption | ✅ Detect & reject |
| IV Generation | Weak random | ✅ random_bytes() |
| Key Derivation | Simple substr | ✅ HKDF/PBKDF2 |
| Legacy Support | N/A | ✅ Auto-detect |
| Batch Ops | ❌ | ✅ encode_many() |
⚠️ Security Best Practices
- Gunakan Key Panjang: Minimal 32 karakter
- Simpan Key Aman: Jangan commit ke Git, gunakan environment variables
- Rotate Key Berkala: Ganti encryption key secara periodik
- HTTPS Always: Kirim data terenkripsi hanya via HTTPS
- Migrasi Data Lama: Segera migrate data legacy ke format baru
📝 Changelog
v2.0.0 (2024)
- ✅ Migrasi penuh dari mcrypt ke OpenSSL
- ✅ Tambah HMAC untuk integritas data
- ✅ Support auto-detect legacy format
- ✅ Batch operations untuk performa
- ✅ PSR-4 autoloading
v1.0.0 (Legacy)
- Original CI3 Encrypt library compatibility
