Yes, it's hex2raw() :

include("misc_func.inc");

x = "4e6573737573";
s = hex2raw(s:x);

In _theory_ using single quoted strings is acceptable :

x = '\x4e\x65\x73\x73\x75\x73';

But in older versions of NASL (pre 2.0.7 if I recall correctly), the
parser _hates_ null terminated strings, so the following :

x = '\x4e\x00\x65';

will actually only be equal to '\x4e'. This has been fixed in newest
releases though.
