This morning Microsoft released updated versions of its JSON Web Token (JWT) library and its OpenID Connect RP library as part of today’s Katana project release. See the Microsoft.Owin.Security.Jwt and Microsoft.Owin.Security.OpenIdConnect packages in the Katana project’s package list. These are .NET 4.5 code under an Apache 2.0 license.

For more background on Katana, you can see this post on Katana design principles and this post on using claims in Web applications. For more on the JWT code, see this post on the previous JWT handler release.

Thanks to Brian Campbell of Ping Identity for performing OpenID Connect interop testing with us prior to the release.
