RZ-AX(1)

💅 NAME

rz-ax — rizin base converter ✨ (yes bestie, it converts bases, and it ate)

---

🎀 SYNOPSIS

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

---

🦋 DESCRIPTION

Okay so, first thing: this command is part of the Rizin project. 🫶

What it does — and this is the iconic part — is let you convert values between positive and negative integer, float, octal, binary, ternary, and hexadecimal values. That's six whole vibes of numbers and rz-ax speaks all of them. No cap. 💜

✨ OPTIONS ✨

• -a — Show ASCII table 👑
• -b — Convert from binary to string, like rz-ax -b 01000101 01110110
• -B — Convert from string to binary, like 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 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) ⭐

Ngl, that's a lot of flags, but each one is a little main character. Collect them all. 💀

🌈 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

Heads up bestie, that Ox12 one — O is a letter, not a zero. Don't come for me, that's literally what the manpage says. 🙈 And yes, z-ax Tx23 is spelled exactly like that too. Copy it as-is and it'll slay. 💖

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

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

You can do 'unpack' hexpair encoded strings easily. Look how cute this is:

$ rz-ax -s 41 42 43
ABC

And it supports some math operations. Fr fr, it does arithmetic:

$ 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. That's the real glow-up — this thing is a workhorse and it knows it. 👑
