QUESTION
I'm using JWKS format to provide from an authentication service the public key that can be used to validate tokens coming from that authentication service. However, to perform validation I need to rebuild the public key from the JWK. How can I convert it?
...ANSWER
Answered 2021-Mar-22 at 01:09I wrote a Go package exactly for this purpose: github.com/MicahParks/keyfunc
*rsa.PublicKey
In this pacakge a JSON Web Key (JWK) looks like this Go struct. It supports both ECDSA and RSA JWK.
QUESTION
As the title says, I have a JSON file generated based on https://mkjwk.org/ and now I want to use the generated values to sign a JWT. I will do this for multiple "clients", each with its own signature. These will then be verified against a set of JWKS containing the public keys for the different "clients".
However, I'm struggling to understand how to use the generated JSON values..
I know I can generate one priv/pub keys directly with the crypto/rsa
module. I've also seen examples where the ppk is given as input in X509 format, though I was trying to avoid it if possible (I guess I'm just being picky as I prefer to be able to read the contents of a file rather than seeing random chars..)
From the multiple examples and numerous searches I've done, I haven't seen one where the process of taking a json file and generating a rsa.privateKey is performed.
I'm also using the jwt-go
and jwx
modules to handle the rest of the use cases, but this one is escaping me..
So, what am I missing? How can I go from a JSON like the one below to a rsa.PrivateKey
?

as for the meanings of keys in json, checkout https://www.javadoc.io/doc/com.nimbusds/nimbus-jose-jwt/5.1/com/nimbusds/jose/jwk/RSAKey.html
I found this just by following source code of mkjwk's cmdline utility

is a base64url encoded representation of the octet key, unless the go interface specifically mentions passing keys in JWK
format, which it doesn't, you need to provide the raw key. base64url.decode()
the k
to get the raw key bytes.
Also, as a sidenote, PBES2-HS256+A128KW
is intended to be used with passwords, not keys, given it's computationally heavy i'd recommend a different key wrapping algorithm (not a symmetric passphrase based one). You can use asymmetric crypto to encrypt for a recipient. And if you also want to achieve authentication of the message, don't use key wrapping at all, use the Direct Key Agreement from JWE instead.
QUESTION
I have private and public key .pem
files that are created within ES256 algorithm. I want to sign JWT token with private key that I can later check with public key.
On jwt.io I found that there are multiple libs that support ES256: jose4j, nimbus-jose-jwt, jjwt, fusionauth-jwt, vertx-auth-jwt. Unfortunately I'm unable to find any examples that load keys from pem file and create JWT token.
Example N1:
I imported pem file into .keystore with
