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
-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.
