How to Initialize AsymmetricJwk about jwt HOT 5 CLOSED

It depends of the cryptographic material at your disposal.
If you have a X509 certificate (X509Certificate2), the easiest way is to use the FromCertificate() method:
var key = RsaJwk.FromX509Certificate(certificate, withPrivateKey: true);

If you have the RSAParameters, use the method FromParameters
var key = RsaJwk.FromParameters(rsaParameters);

If you have the JSON representation in JWK format, use the FromJson method:
var key = RsaJwk.FromJson(jsonString);

Or if you have each component of the RSA key, call the constructor:
var key = new RsaJwk(d: { ... }, p: { ... }, q: { ... }, dp: { ... }, dq: { ... }, qi: { ... }, e: { ... }, n: { ... });
where each parameter is a byte[]

I fear that your RSA key is in PEM format, which is not supported in .Net until the a month ago dotnet/runtime#31201.

i used FromCertificate before creating the issue, google have .p12 file, but they are not recommending it, they are recommending the .json file but that was not in jwk format. The following keys exist in the file
{
"type": "",
"project_id": "",
"private_key_id": "",
"private_key": "",
"client_email": "",
"client_id": "",
"auth_uri": "",
"token_uri": "",
"auth_provider_x509_cert_url": "",
"client_x509_cert_url": ""
}
i know they are providing the ..cert_url from where i can download the JWK formed json file, But instead how can i use private_key(i attached private_key only)? is it possible to retrieve each component of RSA Key?

Thanks

The Google RSA private key is in PKCS8 format, ASN.1 structured.
The client_x509_cert_url provide certificates, but I did not had time to see what kind of key it contain.
This might be the public key as it is exposed on the Internet.

I started to write an ASN.1 parser #441
It will be something like:
RsaJwk.FromPkcs8PrivateKey("The private key");

That would be very nice.It will be available on next version right?
