I’m building a API using Fastify and @fastify/jwt and I’m having trouble specifing which secret I’m going to use to create and verify a JWT.

I have 2 different JWT’s: “refresh-token” and “token”

for “refresh-token” I’m gonna use a JWT_REFRESH_SECRET, and for “token” I’m gonna use “JWT_SECRET”

Here is my “app.ts”, where I configure my fastifyJwt:

app.register(fastifyJwt, { secret: env.JWT_SECRET, cookie:{ cookieName: 'refreshToken', signed: false }, sign: { expiresIn: '10m' } })

using

await request.jwtVerify({ onlyCookie: true })

How can I specify the secret I’m gonna use to decode this JWT?

const token = await reply.jwtSign({ sub: request.user.sub, })

And to create the JWT, how can I specify the secret to create it?

I tried using

await request.jwtVerify({ onlyCookie: true, secret: env.JWT_REFRESH_SECRET })

but I always got an Error
