how can i create RS256Algorithm instance?

[li-zheng-hao]

i create my private key and public key by PuTTY Key Generator tool, the test private key and public key are as follows:

and how can i use this string to create RS256Algorithm instance?

var publicKey=?
var privateKey=?
IJwtAlgorithm algorithm = new RS256Algorithm(publicKey,privateKey); // how to pass two parameters?

Hi, you here to figure out (e.g. search on Stack Overflow) how to create an X509Certificate2 object from the given base64 string. And then pass it to the ctor .

thx @abatishchev , i solve it by this way:

var rs=RSA.Create(2048);
// export string and then save in config file
//privExport= Convert.ToBase64String(rs.ExportRSAPrivateKey());
//pubExport= Convert.ToBase64String(rs.ExportRSAPublicKey());
// import public or private key
rs.ImportRSAPublicKey(Convert.FromBase64String(pubExport), out _);
rs.ImportRSAPrivateKey(Convert.FromBase64String(privExport),out _);

it works well
