[bighamx]

var payload = new Dictionary<string, object>()
{
//xxx
};

var privateKey = ???;
// only got a pem file like
//-----BEGIN PRIVATE KEY-----
//xxxxxxxxxxxxxxx
//-----END PRIVATE KEY-----

//how can i get a key for below jwt token generate

string token = Jose.JWT.Encode(payload, privateKey, JwsAlgorithm.ES384, new Dictionary<string, object>()
{
{ "alg", "ES384" },
{ "type", "JWT" },
});

Hi @bighamx ,

If you can't use any of those due to different .net version, you have to convert it to .p12, you really don't need cert to do that (or you can create any cert out of your key, cert is just bag of attributes, choose any you like, it doesn't matter for your usecase)

openssl pkcs12 -export -nocerts -inkey your.private.key.pem -out your.private.key.p12
