Hi All,
I think Wireshark is a nice hex viewer as well as a packet analyzer, especially for those binary files which consist of several blocks, such as 'tar' format.
Editors which support editing hex file, usually only show binary files in two parts: hex numbers and ascii strings. But wireshark can also show a 'protocol tree' for such binary files.
I've tried a prototype for this (by adding a new WTAP_FILE_ type, and WTAP_ENCAP_ type), it seems that it is very easy to implement the idea.
Any ideas?
