SAPL for .NET

CI NuGet Sapl.Core NuGet Sapl.AspNetCore

.NET implementation of SAPL (Streaming Attribute-Based Access Control).

Built on the SAPL 4.1 enforcement model: a planner-driven constraint architecture that binds handlers to lifecycle signals, streaming enforcement via [StreamEnforce] with support for the new SUSPEND decision verb, and an optional RSocket transport. See the CHANGELOG for the 4.1.0 release notes.

Packages

Package Description
Sapl.Core Framework-agnostic core: PDP client, authorization models, constraint handling, enforcement engine
Sapl.AspNetCore ASP.NET Core integration: filters, attributes, middleware, subscription builder
Sapl.Rsocket RSocket transport for the PDP client, as an alternative to HTTP

Quick Start

dotnet add package Sapl.Core
dotnet add package Sapl.AspNetCore

Demo

See heutelbeck/sapl-dotnet-demos for a full ASP.NET Core example with Keycloak integration, constraint handlers, streaming enforcement, and JWT authorization.
