Some time ago (was lazy to dig history) jwt.Parse was changed to require non-nil keyFunc. This broke `jwt -show` command that prints header and claims and does not validate the token: ``` $ echo $TOKEN | jwt -show - Error: malformed token: token is unverifiable: no keyfunc was provided ``` This change fixes `jwt -show`.
|
Sounds reasonably to me. Can we somehow add a little more documentation to the to itself that the token is only displayed but not verified? |
