Chapter 19: Binary diffing

Radiff is the program used in radare to identify changes and delta offsets between two binary files. It implements different algorithms to find and show this information:

$ radiff -h
Usage: radiff [-c] [-bgeirp] [file-a] [file-b]
  -b   bytediff (faster but doesnt support displacements)
  -d   use gnu diff as backend (default)
  -e   use erg0ts bdiff (c++) as backend
  -p   use program diff (code analysis diff)
  -s   use rsc symdiff
  -S   use rsc symbytediff
  -r   output radare commands
