I'm trying to run this command:

quite work out to do it.

currently it looks like:

executeShell(escapeShellCommand("wget", "-O", "-", url, "|", "gpg", "-D"));

But I can't work out how to pull the string returned with this.

Any help?

executeShell returns the status and the output as a type (perhaps a 
tuple? :) ):

You use the return value for both the status and the output:

    auto wget = executeShell(escapeShellCommand(/* ... */));

    if (wget.status == 0) {
        /* success */
        writeln(wget.output);    // <-- HERE
    }
