— 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 # 4200)
-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 timestamp to string (rz-ax -t 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.
