signatures calculated incorrectly (hexdigest instead of digest) about ruby-jwt HOT 8 CLOSED

No, this looks right. I was just too used to the hexdigest representation of HMAC and the spec was not terribly clear about this. I'm updating my other libs (PyJWT and php-jwt) as well. Can you share a JWT produced with your lib for me to use in my tests? Preferably:

payload json: {"hello": "world"}
key: "secret"
alg: HS256

from ruby-jwt.

Fixed and released. For now I'm using one generated by the fixed version of the library. Hopefully you'd have generated the same:

from ruby-jwt.

I can come close. The spec requires the "issuer" claim, so here's what I get:

Encoded token:
eyJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJpc3N1ZXIiLCJoZWxsbyI6IndvcmxkIn0.DpAMLPYNOvukLtXpEWncK0dOV6vKWvp1KAi8NVcCFcg
Token header:
{"alg":"HS256"}
Token payload:
{"iss":"issuer","hello":"world"}

from ruby-jwt.

Also, thank you for fixing it so fast!

According to the spec, the issuer is optional!

from ruby-jwt.

Right, thanks for catching that. I'll fix that in my code. Now this is the closest I'll get (whitespace is the difference):

Yours:
{"alg": "HS256", "typ": "JWT"}.{"hello": "world"}

Mine:
eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJoZWxsbyI6IndvcmxkIn0.lnneNaoem98xYFES3mi2CJJjnMONuWAu-FTWB3XJN14
{"alg":"HS256","typ":"JWT"}.{"hello":"world"}

BTW the Java library doesn't insert "typ":"JWT" because it's also optional, I just added it here to come closer to your example.

Ah, but it works! So good.

Yes, I'm surprised I decided to include typ by default.

Btw, where's your Java implementation?

from ruby-jwt.

It's this one. It's not "mine" so much as I'm updating it:
