PCAP Sanitization Tool

Log sanitation is a whole lot easier than packets. AFAIK, santizing
pcaps is an intractable problem because of various kinds of encodings
that exist within packets.

Examples:

- FTP IPv4 addresses are comma separated
- DNS does label encoding of domain names (especially with pointers)
- Forwarded emails contain deeply-buried domain names and IP addresses
within gziped, based-64 encoded mime attachments.

So, I don't think you are going to get what you are asking for. That
said, there are tools that can strip out the payload and reassign IP
addresses and port numbers.
