## Name

`jwt-auth` is an authentication plugin that need to work with `consumer'. Add JWT Authentication to a ` service'or `route'.

For more information on JWT, refer to [JWT] (https://jwt.io/) for more information.
## Attributes
* `key` : different `consumer` have different value, it's unique。different `consumer` use the same `key` , and there will be a request matching exception.
* `secret` : optional, encryption key . if you do not specify, the value is auto-generated in the background。
* `algorithm` : optional, encryption algorithm .support`HS256`, `HS384` , `HS512` , `RS256` and `ES256` ,`HS256` is default.
* `exp` : optional, token's expire time, the unit is second。 for example ,5 minutes ,need to set the value of 300.( 5 * 60 = 300 )`。
