(.NET Core C#) RSASSA-PSS Algorithm with SHA256 Hashing
RSA encrypt a SHA256 hash with OAEP padding. Note: This example requires Chilkat v11.0.0 or greater.
bool success = false;
// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
Chilkat.PrivateKey privkey = new Chilkat.PrivateKey();
// Load the private key object from a PEM file.
// (To load from a PEM string, call LoadPem instead.)
success = privkey.LoadPemFile("somePath/myPrivateKey.pem");
if (success == false) {
Debug.WriteLine(privkey.LastErrorText);
return;
}
Chilkat.Rsa rsa = new Chilkat.Rsa();
// Use RSA-PSS by setting OaepPadding = true
rsa.OaepPadding = true;
// Use SHA256
rsa.OaepHash = "SHA-256";
rsa.UsePrivateKey(privkey);
// Generate a base64 signature.
rsa.EncodingMode = "base64";
string sigStr = rsa.SignStringENC("String to be signed","SHA-256");
if (rsa.LastMethodSuccess == false) {
Debug.WriteLine(rsa.LastErrorText);
return;
}
Debug.WriteLine("Signature: " + sigStr);
