Getting System.NullReferenceException

[jhakasjk]

I'm getting below exception while trying to decrypt the string. "System.NullReferenceException: Object reference not set to an instance of an object.\r\n at CoreEntities.Classes.Utility.RSADecrypt(String input)\r\n at WebAPI.Attributes.ApiAuthorizeAttribute.Authorize(HttpActionContext actionContext)"

Code:-

public static string RSADecrypt(string input)
        {
            try
            {
                string priv = File.ReadAllText(HostingEnvironment.MapPath("~/Certificates/consumer.pem"));
                RSACryptoServiceProvider privc = Crypto.DecodeRsaPrivateKey(priv);
                return Crypto.DecryptString(input, privc);
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }

It is only coming when i deploy my application on windows server 2012 although it's working fine on local machine on iis and via visual studio 2015.

How to fix this?
