## JsonWebKeyPropertyNames Class

JSON property names used in the JSON serialization of a JWK as defined in RFC 7517 Section 4
and RFC 7518 Section 6\. These are the wire\-level names; consumers normally interact with the
strongly\-typed properties on [JsonWebKey](https://www.abblix.com/en/docs/api/abblix-jwt/Abblix.Jwt.JsonWebKey 'Abblix\.Jwt\.JsonWebKey') and its subclasses\.

```csharp
public static class JsonWebKeyPropertyNames
```

Inheritance [System\.Object](https://learn.microsoft.com/en-us/dotnet/api/system.object 'System\.Object') → JsonWebKeyPropertyNames
