I think the best you can do is this:

========================
import std.stdio;

struct KryptedString(string value)
{
     alias get this;
     string get() @property
     {
         return "decrypt \"" ~ value ~ "\" here";
     }
}

template krypt(string value)
{
     string process()
     {
         return "crypted"; // encrypt the template param
     }
     enum krypt = KryptedString!process();
}

enum string1 = krypt!"blablabla";
enum string2 = krypt!"blablablabla";

void main()
{
     writeln(string1);
     writeln(string2);
}
========================

The syntax is not so bad.

    enum KryptedString string1 = "blablabla";

is impossible or maybe I don't know the trick yet.
