I'm working with a string created with hexstr(). I've done some work on the hex values, now I want to convert back to ASCII. Say I have a string "4c444150",is there function available to convert back to ASCII? Maybe I missed something in the NASL2 ref?

Also, I've made an effort to perform the conversion by incrementing through a string by twos and preceding the characters with \x. However, the following code snip will produce \x4c\x44\x41\x50, not the ASCII string "LDAP" as I would like.

For example:

version = "4c444150";
i = 0;
f = 1;
while (f <= strlen(version)) {
x = version[i];
y = version[f];
z =  string("\x" + x + y);
conv = string(z); 
display(conv);
i = i + 2;
f = f + 2;
}

--> displays \x4c\x44\x41\x50

This will display the ASCII values however.

a = "\x4c\x44\x41\x50";
b = string(a);
display(b, "\n");

--> displays LDAP

What am I doing wrong?
