NAME
rax2 — radare base converter
SYNOPSIS
rax2 [−ebBsSvxkKh] [[expr] ...]
DESCRIPTION
This command is part of the radare project.
This command allows you to convert values between positive and negative integer, float, octal, binary and hexadecimal values.
OPTIONS
−b
Convert from binary string to character (rax2 −b 01000101)
−k
Keep the same base as the input data
−e
Swap endian.
−F
Read C strings from stdin and output in hexpairs. Useful to load shellcodes
−i
Dump stdin to C array in stdout (xxd replacement)
−I
Convert LONG to/from IP ADDRESS
−l
Append newline to the decoded output for human friendly-ness
−K
Show randomart key asciiart for values or hexpairs
−r
Show the same output as the r2’s ‘? 0x804‘ command. When combined with -S (-rS) it will print r2 commands to write the actual binary into radare2
−s
Convert from hex string to character (rax2 −s 43 4a 50)
−S
Convert from character to hex string (rax2 −S C J P)
−n
Show hexpairs from integer value
−N
Show hexadecimal C string from integer value
−u
Convert given value to human readable units format
−v
Show program version
−x
Convert a string into a hash
−h
Show usage help message
−o
Convert from octal string to char (rax2 -o 162 62)
USAGE
Force output mode (numeric base)
=f floating
point
=2 binary
=3 ternary
=8 octal
=10 decimal
=16 hexadecimal
Available variable types are:
int −>
hex rax2 10
hex −> int rax2 0xa
−int −> hex rax2 −77
−hex −> int rax2 0xffffffb3
int −> bin rax2 b30
bin −> int rax2 1010d
float −> hex rax2 3.33f
hex −> float rax2 Fx40551ed8
oct −> hex rax2 35o
hex −> oct rax2 Ox12 (O is a letter)
bin −> hex rax2 1100011b
hex −> bin rax2 Bx63
With no arguments, rax2 reads values from stdin. You can pass one or more values as arguments.
$ rax2 33 0x41
0101b
0x21
65
0x5
You can do ’unpack’ hexpair encoded strings easily.
$ rax2 −s
41 42 43
ABC
And it supports some math operations.
$ rax2
0x5*101b+5
30
It is a very useful tool for scripting, so you can read floating point values, or get the integer offset of a jump or a stack delta when analyzing programs.
