Re: SSL worm sigs

The "fences" in things like this: "|0d 0a|" are delimiters to indicate hex byte values instead of litteral text. So that string matches a 2 character sequence, consisting of a CR and a LF. Whereas "0d 0a" matches a 5 byte sequence consisting of ascii zero, ascii d, ascii space.. etc.

Are the fences around the actual signature part of the signatue, or are they
delimiters used by snort?
