The secret used to sign JWT tokens with. 2. In the case where the secret key is not Base64 encoded, we can invoke the getByte() method on the plain string: private Key getSigningKey() { byte[] keyBytes = this. ; Length : In the example, I've used 40 which just means 40 random bytes will be generated and that will be It is important to know how to generate a JWT token, as the Network APIs use them to perform authorization. So only this data plus the secret can create this signature. To access the API Key and Secret, Create a JWT App on the Marketplace. pubKey: A public key for verifying JWT tokens, if using asymmetric verification; jwt.
