I am trying to write a wrapper script to start an ncat listener. I don't want to have to output the certificate and key to a file, rather I'd like to store it as a variable within the script, and call it like this:

```
#!/bin/bash

crt="(           ---BEGIN CERT ----
MIICjdkfj4544757jkdfjdkfjsfsdkljf4alwjkqe3r3lkfd
dfjsdkfjdkfjdkfjdf34534235jeklgjeg94gjriogjgojdgkdo7HH
87HSKRNSSFSDFJDKDJFKJDSF/7387dfddffdfd8jhrg8hgs....etc")

ncat --listen --ssl --ssl-cert "$crt" --ssl-key "$key" 127.0.0.1 4444

```

But ncat (or bash) keep interpretting the key as a super long file name, rather than the key itself. Basically I want to store the key and cert as variables, and have ncat read them as if it was reading it from an actual file. Is this possible? I've tried several different methods, and have had no luck yet.
