Branca.NET Test Tool

An online test tool for creating and decrypting Branca tokens. Useful for testing your own Branca implementation against or just seeing what the Branca format looks like. Implemented in .NET using ScottBrady.IdentityModel.

Branca is a simple token that uses symmetric encryption. I typically recommend its use over a JWT signed with an HMAC; another alternative being JWE. To learn more about Branca and when to use it, check out my article on alternatives to JWTs.
