What I ended up doing is create a new KeyContainer name based off of the current DateTime (DateTime.Now.Ticks.ToString()) whenever I need to create a new key and save the container name and public key to the database. Also, whenever I create a new key I would do the following:
public static string ConvertToNewKey(string oldPrivateKey)
{
// get the current container name from the database...
rsa.PersistKeyInCsp = false;
rsa.Clear();
rsa = null;
string privateKey = AssignNewKey(true); // create the new public key and container name and write them to the database...
// re-encrypt existing data to use the new keys and write to database...
return privateKey;
}
public static string AssignNewKey(bool ReturnPrivateKey){
string containerName = DateTime.Now.Ticks.ToString();
// create the new key...
// saves container name and public key to database...
// and returns Private Key XML.
}
before creating the new key.
