Howdy, was hoping someone might be able to help me
Howdy, was hoping someone might be able to help me with getting the OAuth2 working. I'm using NodeJS to create the token and hit the api, but I've been stuck at trying to get the signature correct.
I'm not quite sure what I'm doing wrong when creating the signature.
```var jwtHeader = {
'alg': 'RS256',
'typ': 'JWT',
'kid': ck.keyid
}
var jwtData = {
'aud': ck.clientid,
'sub': 'apigee',
'iss': ck.issuer,
'iat': currentTimestamp,
'exp': currentTimestamp + 3600
}
const b64Header = toBase64 (jwtHeader);
const jwtB64Header = replaceSpecialChars(b64Header);
const b64Payload = toBase64 (jwtData);
const jwtB64Payload = replaceSpecialChars (b64Payload);
const toSign = jwtB64Header + '.' + jwtB64Payload
const sign = crypto.createSign('SHA256')
sign.update(toSign)
const verify = crypto.createVerify('SHA256');
verify.update(toSign)
const signature = sign.sign({key: privateKey, passphrase: 'passwordhere'})
console.log("Verified?")
console.log(verify.verify(publicKey, signature, 'SHA256'));
const token = toSign + "." + replaceSpecialChars(toBase64(signature));```
