RAX2(1) 						    BSD General Commands Manual 						   RAX2(1)

NAME

     rax2 -- radare base converter

SYNOPSIS

     rax2 [-ebsSvxkh] [[value] ...]

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

     -e 	 Swap endian.

     -b 	 Convert from binary string to caracter (rax2 -b 01000101)

     -s 	 Convert from hex string to caracter (rax2 -s 43 4a 50)

     -S 	 Convert from hex string to caracter (rax2 -S C J P)

     -v 	 Show program version

     -x 	 Convert a string into a hash

     -k 	 Keep de same base as the input data

     -h 	 Show usage help message

USAGE

     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 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 ana-
     lyzing programs.

base32::hex(n)							  Base32 encoding						    base32::hex(n)

NAME

       base32::hex - base32 extended hex encoding

SYNOPSIS

       package require Tcl  8.4

       package require base32::core  ?0.1?

       package require base32::hex  ?0.1?

       ::base32::hex::encode string

       ::base32::hex::decode estring

_________________________________________________________________

DESCRIPTION

       This  package  provides	commands for encoding and decoding of strings into and out of the extended hex base32 encoding as specified in the
       RFC 3548bis draft.

API

       ::base32::hex::encode string
	      This command encodes the given string in extended hex base32 and returns the encoded string as its result. The result may be  padded
	      with the character = to signal a partial encoding at the end of the input string.

       ::base32::hex::decode estring
	      This  commands  takes  the  estring  and	decodes it under the assumption that it is a valid extended hex base32 encoded string. The
	      result of the decoding is returned as the result of the command.

	      Note that while the encoder will generate only uppercase characters this decoder accepts input in lowercase as well.

	      The command will always throw an error whenever encountering conditions which signal some type of bogus input, namely if

	      [1]    the input contains characters which are not valid output of a extended hex base32 encoder,

	      [2]    the length of the input is not a multiple of eight,

	      [3]    padding appears not at the end of input, but in the middle,

	      [4]    the padding has not of length six, four, three, or one characters,

CODE MAP

       The code map used to convert 5-bit sequences is shown below, with the numeric id of the bit sequences to the left and the character used to
       encode it to the right. The important feature of the extended hex mapping is that the first 16 codes map to the digits and hex characters.
