Hi Team,

I have a response from the external API in the below format:

const inputData = {
signature: 'eyJhbGciOiJSUzI1NiIsImtpZCI6InNhbXBsZS1rZXktaWQifQ..SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c',
response: 'jdskhfgdjskfgkjsdhf'
};
The signature is without the payload check ("..") in inputData signature, and I am trying to verify the signature.

My public key format is:

PublicKey: {
"kty": "RSA",
"e": "AQAB",
"use": "sig",
"kid": "erityuiuerot",
"n": "kjfghdsjkbfdasbf"
}
The inputData is:

const inputData = {
signature: 'eyJhbGciOiJSUzI1NiIsImtpZCI6InNhbXBsZS1rZXktaWQifQ..SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c',
response: 'jdskhfgdjskfgkjsdhf'
};
I am using the below code to verify it in nodejs:

const jose = require("node-jose");

async function createKeystore() {
const keystore = jose.JWK.createKeyStore();

// Add the public key to the keystore
const key = await keystore.add({
    kty: 'RSA',
    kid: "erityuiuerot",
    use: 'sig',
    alg: 'RS256',
    n: "kjfghdsjkbfdasbf",
    e: 'AQAB'
}, 'json');

return keystore;

}

async function verifyDetachedJWS(jws, payload) {
try {
const keystore = await createKeystore();
console.log("keystore", keystore);
// Use JWS.createVerify to verify the token
const verifier = jose.JWS.createVerify(keystore);

   const result = await verifier.verify(jws);

    console.log('Verification successful:', result);
} catch (error) {
    console.error('Verification failed:', error);
}

}

// Example JWS token (without payload) and payload (replace with your actual values)
const jws = 'eyJhbGciOiJSUzI1NiIsImtpZCI6InNhbXBsZS1rZXktaWQifQ..SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c';

verifyDetachedJWS(jws, payload);
But I am getting the following error:

Verification failed: Error: no key found
at processSig (/node_modules/node-jose/lib/jws/verify.js:132:22)
I am unable to figure out where the issue is. Can you please help me resolve this as soon as possible?

Do I need to use private for verification, if yes then please suggest code how to do it.

my private key is in below format :

PrivateKey : {
keys : [{
"p": "",
"kty": "RSA",
"q": "",
"d": "",
"e": "",
"use": "sig",
"kid": "",
"qi": "",
"dp": "",
"dq": "",
"n": ""
}]
};

Kindest Regards
