# rz-ax(1)

rizin base converter

## NAME

**rz-ax** – rizin base converter

## SYNOPSIS

**rz-ax** \[**-ebBdDeEfFhiIklLosStuvwx**\] \[\[expr\] ...\]

## DESCRIPTION

This command is part of the Rizin project.

This command allows you to convert values between positive and negative integer, float, octal, binary, ternary, and hexadecimal values.

## OPTIONS

- **-a**

  Show ASCII table

- **-b**

  Convert from binary to string (rz-ax -b 01000101 01110110)

- **-B**

  Convert from string to binary (rz-ax -B hello)

- **-d**

  Force output as integer (rz-ax -d 3 outputs 3 instead of 0x3)

- **-D**

  Base64 decode

- **-e**

  Swap endianness (rz-ax -e 0x33)

- **-E**

  Base64 encode

- **-f**

  Floating point arithmetic (rz-ax -f 6.3+2.1)

- **-F**

  Read C strings from stdin and output in hexpairs. Useful to load shellcodes (rz-ax -F \< shellcode.\[c/py/js\])

- **-h**

  Show usage help message

- **-i**

  Dump stdin to C array in stdout (rz-ax -i \< bytes)

- **-I**

  Convert LONG to/from IP ADDRESS (rz-ax -I 3530468537)

- **-k**

  Keep the same base as the input data (rz-ax -k 33+3 -\> 36)

- **-l**

  Append newline to the decoded output

- **-L**

  Convert binary to hexadecimal (rz-ax -L 111111111 outputs 0x1ff)

- **-n**

  Show hexpairs from integer value (rz-ax -n 0x1234 # 34120000)

- **-N**

  Show hex C string from integer value (rz-ax -N 0x1234 #

- **-o**

  Convert from octal string to char (rz-ax -o 162 172 # rz)

- **-r**

  Rz style output (rz-ax -r 0x1234)

- **-s**

  Convert from hex string to character (rz-ax -s 43 4a 50)

- **-S**

  Convert from character to hex string (rz-ax -S \< /bin/ls \> ls.hex)

- **-t**

  Convert Unix timestamp to string (rz-ax -t 1234567890)

- **-m**

  Convert MS-DOS timestamp to string (rz-ax -m 0x12345678)

- **-W**

  Convert Win32 timestamp to string (rz-ax -W 1234567890)

- **-u**

  Convert given value to human readable units format (rz-ax -u 389289238 # 317.0M)

- **-v**

  Show version information

- **-w**

  Convert signed word (rz-ax -w 16 0xffff)

- **-x**

  Convert a string into a hash (rz-ax -x linux osx)

- **-p**

  Show position of set bits in the binary representation (rz-ax -p 0xb3)

## 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     rz-ax 10\
   hex     -\>  int     rz-ax 0xa\
   \-int    -\>  hex     rz-ax -77\
   \-hex    -\>  int     rz-ax 0xffffffb3\
   int     -\>  bin     rz-ax b30\
   int     -\>  ternary rz-ax t42\
   ternary -\>  int     rz-ax 1010dt\
   bin     -\>  int     rz-ax 1010d\
   float   -\>  hex     rz-ax 3.33f\
   hex     -\>  float   rz-ax Fx40551ed8\
   oct     -\>  hex     rz-ax 35o\
   hex     -\>  oct     rz-ax Ox12 (O is a letter)\
   bin     -\>  hex     rz-ax 1100011b\
   hex     -\>  bin     rz-ax Bx63\
   ternary -\>  hex     rz-ax 212t\
   hex     -\>  ternary z-ax Tx23\
   raw     -\>  hex     rz-ax -S \< /binfile\
   hex     -\>  raw     rz-ax -s 414141

With no arguments, rz-ax read values from stdin. You can pass one or more values as arguments.

  $ rz-ax 33 0x41 0101b\
   0x21\
   65\
   0x5

You can do 'unpack' hexpair encoded strings easily.

  $ rz-ax -s 41 42 43\
   ABC

And it supports some math operations.

  $ rz-ax\
   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.
