From: Tony Johansson on 20 Apr 2010 09:24 Hi! Why do I get the same private key when I run this program several times even if I shutdown the computer and start all over again I get the same private key as I get the first time. static void Main(string[] args) { CspParameters persistentCsp = new CspParameters(); persistentCsp.KeyContainerName = "AssymetricExample"; RSACryptoServiceProvider myRSA = new RSACryptoServiceProvider(persistentCsp); myRSA.PersistKeyInCsp = true; RSAParameters privateKey = myRSA.ExportParameters(true); foreach (byte thisByte in privateKey.D) Console.WriteLine(thisByte.ToString("X2") + " "); } //Tony
