I am developing an encryption decryption software.I used RSA encryption to encypt my symmetric key.

I followed the code provided in the link

https://msdn.microsoft.com/en-us/library/bb397867(v=vs.110).aspx[^]

My encryption and decryption done successfully in same machine.But when I tried to decrypt from other computer,an error :bad data is occuring.(It can be decrypted from same machine.)

How to publish my public key to other systems inorder to decrypt form different system.



Please help me ,give me an idea to decrypt from different machines.

public void GetPrivateKey()
        {
            string c;
           
            cspp.KeyContainerName = keyName;

            rsa = new RSACryptoServiceProvider(cspp);
            rsa.PersistKeyInCsp = true;
            
            if (rsa.PublicOnly == true)
                c= "Key: " + cspp.KeyContainerName + " - Public Only";
            else
                c = "Key: " + cspp.KeyContainerName + " - Full Key Pair";
        }
 public string decryptkey(string at)
        {
            byte[] KeyEncrypted;
            KeyEncrypted = File.ReadAllBytes(at);
            //System.IO.File.ReadAllBytes(at);//for good 
           
            objr.GetPrivateKey();
           byte[] KeyDecrypted = objr.rsa.Decrypt(KeyEncrypted, false);
            string skey = GetString(KeyDecrypted);
            return skey;
        }

Bad data Error happens in this line,
byte[] KeyDecrypted = objr.rsa.Decrypt(KeyEncrypted, false);.


Please..
