# rusty-radamsa

Radamsa ported to rust lang



Rusty Radamsa is a general purpose fuzzer. It modifies given sample data

in ways, which might expose errors in programs intended to process

the data. For more information, read the fine manual page, or visit

https://gitlab.com/akihe/radamsa.



Rusty Radamsa was written by Amanda Rousseau (malwareunicorn), based on Radamsa by Aki Helin, initially at OUSPG.



## Requirements:

Supported operating systems:

 * GNU/Linux

 * OpenBSD 

 * FreeBSD

 * Mac OS X

 * Windows



Software requirments:

* Rustlang 1.66

* Cargo



## Building Radamsa

```text

git clone 

cd rusty-radamsa

cargo build

```



## Usage: 

```text

rustyradamsa.exe [OPTIONS] [FILE]... [COMMAND]

```



## Commands:

```text

  list

          list mutations, patterns and generators

  help

          Print this message or the help of the given subcommand(s)

```



## Arguments:

```text

  [FILE]...

          file or directory as generator input. example: "./input/* test.bin"

```



## Options:

```text

-s, --seed 

          random seed (u64, default random)



  -n, --count 

          how many outputs to generate (u64)



  -H, --hash 

          hash algorithm for uniqueness checks (default sha256)



  -p, --patterns 

          which mutation patterns to use (use list command to see all hashes)

          [default: 0]



  -S, --seek

## Lib Examples

```

use std::boxed::Box;

extern crate rusty_radamsa;

let data = Box::<[u8]>::from("Hello World 12345689\n".as_bytes());

let mut out_buffer = Box::<[u8]>::from(vec![0u8; 2048]);

let max_len = out_buffer.len(); //aka truncate

let seed: u64 = 42;

let _len = rusty_radamsa::radamsa(&data, data.len(), &mut out_buffer, max_len, seed);

```

## TODOs:

* Seek to test case

* Templated filenames for output

* Template output (--output-template)

* Delay between mutations (--delay)

* Pcapng generator (pcapng)

* Jump generator (jump)

* Saving metadata (--meta)

* Mutator: Xml (xp)

* Mutator: Byte inversion 

* Mutator: Even powers of two

* Mutator: Add/subtract a random value from 0..16

* Mutator: Overwrite contents with zero bytes

* Fix generic mutators to be stateful

* Make the mutation hash global for external use
