# JWT
|
||||
|
||||
|
||||
[](https://gofiber.io/discord)
|
||||
|
||||
|
||||
|
||||
|
||||
JWT returns a JSON Web Token (JWT) auth middleware.
|
||||
For valid token, it sets the user in Ctx.Locals and calls next handler.
|
||||
For invalid token, it returns "401 - Unauthorized" error.
|
||||
For missing token, it returns "400 - Bad Request" error.
|
||||

||||

|
||||
|
||||
**Note: Requires Go 1.19 and above**
|
||||
|
||||
## Install

|

|
||||
## RS256 Test
|
||||
The RS256 is actually identical to the HS256 test above.
|
||||
|
||||
## JWK Set Test
|
||||
The tests are identical to basic `JWT` tests above, with exception that `JWKSetURLs` to valid public keys collection in JSON Web Key (JWK) Set format should be supplied. See [RFC 7517](https://www.rfc-editor.org/rfc/rfc7517).
|
||||
|
||||
## Custom KeyFunc example
|
||||
|
||||
KeyFunc defines a user-defined function that supplies the public key for a token validation.
|
||||
The function shall take care of verifying the signing algorithm and selecting the proper key.
|
||||
A user-defined KeyFunc can be useful if tokens are issued by an external party.
|
||||
|
||||
When a user-defined KeyFunc is provided, SigningKey, SigningKeys, and SigningMethod are ignored.
|
||||
This is one of the three options to provide a token validation key.
|
||||
The order of precedence is a user-defined KeyFunc, SigningKeys and SigningKey.
|
||||
Required if neither SigningKeys nor SigningKey is provided.
|
||||
Default to an internal implementation verifying the signing algorithm and selecting the proper key.

||||

||||
