Propagation Signing¶

ContextR.Propagation.Signing provides HMAC-based tamper detection for context headers across service boundaries.

Back to Packages Overview

Use This Package When¶

context flows across multiple services and must not be modified in transit
you need tamper detection independent of transport security (defense-in-depth)
context crosses untrusted or semi-trusted network boundaries

Install¶

dotnet add package ContextR.Propagation.Signing

Quick Start¶

builder.Services.AddContextR(ctx =>
{
    ctx.Add<TenantContext>(reg => reg
        .MapProperty(c => c.TenantId, "X-Tenant-Id")
        .MapProperty(c => c.Region, "X-Region")
        .UseContextSigning<TenantContext>(o =>
            o.Key = Convert.FromBase64String("your-base64-key-here"))
        .UseAspNetCore()
        .UseGlobalHttpPropagation());
});

No custom key provider needed — keys are configured inline.
