CryptoMode Enum

Defines the cryptographic mode for all operations.


Definition

namespace WvdS.System.Security.Cryptography
 
public enum CryptoMode

Fields

Name Value Description
Classic 0 Classic algorithms only (RSA, ECDSA). No PQ extensions.
Hybrid 1 Classic + PQ combined. RSA/ECDSA signature plus ML-DSA signature. Recommended.
PostQuantum 2 PQ algorithms only (ML-DSA, ML-KEM). No classic algorithms.

Remarks

Classic

Uses only standard .NET cryptography. No change to the behavior of extended methods.

Hybrid

Creates hybrid signatures and certificates:

  • Classic signature (RSA/ECDSA) for backward compatibility
  • PQ signature (ML-DSA) as X.509 extension

Classic clients can validate hybrid certificates (ignoring the PQ extension).

PostQuantum

Uses exclusively PQ algorithms. Only for environments where all participants are PQ-capable.


Example

using WvdS.System.Security.Cryptography;
 
// Set globally
CryptoConfig.DefaultMode = CryptoMode.Hybrid;
 
// Or per operation
var cert = request.CreateSelfSigned(
    notBefore,
    notAfter,
    CryptoMode.PostQuantum);
