Active Key Mode: RSA-4096
The application successfully detected the **RSA** key path. However, for the actual key wrapping operation, standard PHP currently relies on OpenSSL's RSA-like function because native Kyber KEM functions (needed for true PQC) are not built into standard PHP. True quantum-safe cryptography requires the **`oqs-php` extension** to be installed alongside PQC keys.
Uses a three-factor scheme: Server Private Key + User Password + Key Protector File. The **User Password** protection ensures file security even if the server's Private Key is compromised.
