RADIFF2unified binary diffing utility


radiff2 [-AabcCdDhOrspxvz] [-t 0-100] [-g sym] [-S algo] file1 file2


radiff2 implements many binary diffing algorithms for data and code.

Analyze binary after loading it with RCore (see -C) and use -AA to run aaaa instead of aaa.
Specify architecture (x86, arm, ..)
Select register size bits for given arch
Count number of differences.
Specify eval config vars for all RCore instances created.
Code diffing using graphdiff algorithm. Output columns are: file-a-address, percentatge of most similar function in B file | file-b-address. (Use with -A to analyze the binaries to find more functions)
Use delta diffing (slower).
Show disasm instead of hexpairs (honors -a arch and -b bits)
sym | off1,off2
Graph diff output of given symbol, or between two functions, at given offsets: one for each binary.
Show usage help message.
Compare the list of imports
Suppress address names (show only addresses) when code diffing.
Do code diffing with all bytes instead of just the fixed opcode bytes
Use physical addressing (
Quiet mode: disable colors and reduce output
Output in radare commands as a binary patch.
Show two column hexdump diffing.
Calculate text distance from two files.
Same as before but using the Levenstein algorithm (faster but sometimes buggy)
[name, namelen, dist, size, ...]
Specify which column of the code diffing algo use for diffing
Choose matching threshold for binary code diffing
Unified diff output
Unified diff output using system´s diff program
Show version information.
Be verbose sometimes
Perform diff on extracted strings
