I'm trying to implement WebSocket handshake (76) in ObjC and can't figure out (as I'm new to C and ObjC) how can I get the following:

1. List item
2. I've got two number

```
155712099
173347027

```
3. I need to convert them to 32 bit big-endian numbers
4. concatenate them into a string
5. and express the resulting string in ASCII

Help is highly appreciated.
