CAPTCHA

C# .NET 9.0 Blazor server component for hCaptcha.

Installation

NuGet Package

NuGet CLI
dotnet add package ChatAIze.Captcha

Service (Program.cs)

builder.Services.AddCaptcha(o =>
{
    o.SiteKey = builder.Configuration["Captcha:SiteKey"]!;
    o.Secret = builder.Configuration["Captcha:Secret"]!;

    o.IsConnectionProxied = false; // optional, default is false
