JwtHeader Class

The JwtHeader class contains JSON objects that represent the cryptographic operations applied to the JSON Web Token (JWT) and optionally any additional properties of the JWT.

Remarks

The member names within the JWT Header are referred to as Header Parameter Names. These names must be unique and the values must be of type String. The corresponding values are referred to as Header Parameter Values.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
