How to use RSA_PRIVATE_KEY in nodejs for JWT?

Question

I'm following angular documentation https://blog.angular-university.io/angular-jwt-authentication/ in step 2 uses RSA_PRIVATE_KEY but it doesn't explain how to generate it, I have to install something to use

const RSA_PRIVATE_KEY = fs.readFileSync (' ./ demos / private.key ');? 

Thanks

You need OpenSSL binary to generate the keys:

openssl genpkey -out private.pem -aes256 -algorithm rsa -pkeyopt rsa_keygen_bits:4096
openssl pkey -in private.pem -out public.pem -pubout

You're welcome ;)
