radiff2 implements many binary diffing algorithms for data and code.


Binary output (GDIFF format)


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

-B baddr

Specify the base address to add to the offsets in the diff listings


Count number of differences.

-e -[k=v]

Specify eval config vars for all RCore instances created.


Code diffing using graphdiff algorithm. Output columns are: file-a-address, percentage 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)

-g sym | off1,off2

Graph diff output of given symbol, or between two functions, at given offsets: one for each binary.

-G [cmd]

Run given command after creating each core instance


Show usage help message.

-i i, s, c, m, f

Compare (i)mports, (s)ymbols, (c)lassnames, (m)ethods, (f)ields from given files (radiff2 -ii /bin/ls /bin/cat)


Use JSON for output


Suppress address names (show only addresses) when code diffing.


Do code diffing with opcode bytes only.

-m [graphmode]

Specify the graph mode (i)nteractive, (k)ey-value, (j)son, (J)son2, (t)iny, (d)ot, (s)tar, (g)ml, (m)ermaid


Use physical addressing (io.va=0)


Quiet mode: disable colors and reduce output


Output in radare commands as a binary patch.


Show two column hexdump diffing.


Show two column hexII diffing.


Compute edit distance (no substitution, Eugene W. Myers' O(ND) diff algorithm) between two files.


Compute Levenshtein edit distance (substitution is allowed, O(N^2)) between two files.

-S [name, namelen, dist, size, ...]

Specify which column of the code diffing algo use for diffing

-t 0-100

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


Perform diff using zignatures instead of function list (NEW)
