📦 Package Overview

Authlink.Policy.Client.Core is a low-level, dependency-free library that defines interfaces, data contracts, and shared models used by client SDKs integrating with the Authlink Policy Decision Point (PDP).

It is intended to be consumed by higher-level packages such as:

  • Authlink.Policy.Client.Http
  • Authlink.Policy.Client.ServiceStack

🚀 Install

dotnet add package Authlink.Policy.Client.Core

Or via Package Manager:

PM> Install-Package Authlink.Policy.Client.Core

🔧 Purpose

This package serves as a foundation layer, enabling:

  • Abstraction of policy‐decision flows (Allow/Deny)
  • Typed obligation contracts (ObligationDto, ObligationType) returned with allow decisions
  • Decoupled, testable client implementations
  • Plug-and-play support across .NET environments (console, web, serverless)
  • Zero runtime dependencies beyond .NET Standard

⚖️ Obligations (since 1.3.0)

An allow decision may carry obligations the consumer (PEP) must honour before completing the operation. Each obligation is a kind plus a flat bag of string attributes:

Kind Attributes Meaning
RowFilter expression, version Restrict the result set to rows satisfying the expression
MaskProperties properties, version Mask every property matched by the selector list
RequireAudit (none) Record an audit entry for the operation
RequireReason (none) Capture a caller-supplied reason

Expression payloads follow the normative obligation expression grammar (versioned via the version attribute; currently "1"). PolicyDecisionResponse.ObligationsGrammarVersion carries the grammar version the PDP serves whenever a decision has obligations, so consumers can detect a contract they do not support up front.

Fail closed: a consumer that cannot fully enforce an obligation — unknown kind, unsupported grammar version, or an unparseable expression — must deny the request. Partial enforcement is not permitted. The normative grammar reference lives in the Authlink repository at docs/specifications/obligation-expression-grammar-v1.md.

Authlink.Policy.Client.Http

Implements the IPolicyClient abstraction over HTTP, allowing .NET applications to call Authlink�s Policy Decision Point (PDP) via a lightweight, HttpClientFactory-powered client. Includes PolicyHttpClient, option-based configuration (base URI, default client-ID, timeout), JSON (de)serialization of decision requests, and fail-closed error handling. Designed to plug into ASP.NET Core, ServiceStack, worker services, or any .NET runtime in combination with Authlink.Policy.Client.Core.
