====== CryptoConfig.EnablePostQuantum Method ======

Enables post-quantum cryptography and initializes the OpenSSL interop.

----

===== Definition =====

<code csharp>
namespace WvdS.System.Security.Cryptography

public static void EnablePostQuantum(CryptoMode mode = CryptoMode.Hybrid)
</code>

----

===== Parameters =====

^  Name  ^  Type  ^  Description  ^
| mode | [[..:cryptomode|CryptoMode]] | The mode to enable. Default: ''CryptoMode.Hybrid'' |

----

===== Remarks =====

This method is a convenience function that:
  - Sets ''DefaultMode'' to the specified value
  - Initializes OpenSSL and checks the version
  - Loads the crypto provider

Equivalent to:
<code csharp>
CryptoConfig.DefaultMode = mode;
CryptoProviderFactory.GetProvider().Initialize();
</code>

----

===== Examples =====

==== Standard (Hybrid) ====

<code csharp>
// Enables Hybrid mode
CryptoConfig.EnablePostQuantum();

// Equivalent to:
CryptoConfig.EnablePostQuantum(CryptoMode.Hybrid);
</code>

==== PostQuantum-Only ====

<code csharp>
// Only for fully PQ-capable environments
CryptoConfig.EnablePostQuantum(CryptoMode.PostQuantum);
</code>

----

===== Exceptions =====

| DllNotFoundException | OpenSSL library not found |
| InvalidOperationException | OpenSSL version < 3.6 or PQ algorithms not available |
