OAEP padding error

Alo!
Uporabljam za enkripcijo parametrov RSA kritpo algoritem. Skriptira mi ga vredi, potem pa pri dekripciji dobim tole napako. Zanima me, v cem sem zgresil? a je treba se kaj nastavt, kaksne pravice na network service dodat al pa kaj drugega?

Koda:
 /// <summary>
        /// private and public keys
        /// </summary>
        private static RSAParameters paramPublic, paramPrivate;

        /// <summary>
        /// decrypt parameter to normal state
        /// </summary>
        /// <param name="parameter">parameter to decyrpt</param>
        /// <returns>get valid normal string or throw exception otherwise</returns>
        public static string DecryptParameters( string parameter )
        {  
            try
            {
                RSACryptoServiceProvider cyrpto = new RSACryptoServiceProvider();
                cyrpto.ImportParameters(paramPrivate); //get private key
                //encode string
                byte[] decryptedValue = cyrpto.Decrypt(Encoding.Unicode.GetBytes(parameter), true);
                //return value
                return Encoding.Unicode.GetString(decryptedValue);
            }
            catch (CryptographicException error)
            {
                throw new Luis.LuisException(error.Message, ErrorTypes.CYRPTOGRPHIC_ERROR);
            }                                                                
        }

Poizkusi z različnimi možnostmi &quot;PaddingMode&quot; parametra.Sedaj ko sem pa pogledal kodo pa vidim, da je verjetno problem v tem:&nbsp;&nbsp;&nbsp; namesto encoding.unicode uporabljal raje Convert.FromBase64String&nbsp;&nbsp;
