# zip-password-finder
[](https://github.com/agourlay/zip-password-finder/actions/workflows/ci.yml)
[](https://crates.io/crates/zip-password-finder)
`zip-password-finder` is a tool to find the password of protected zip files.
The design of this tool is described in details in the following blog articles:
- [Brute forcing protected ZIP archives in Rust](https://agourlay.github.io/brute-forcing-protected-zip-rust/)
- [Follow up on cracking ZIP archives in Rust](https://agourlay.github.io/follow-up-cracking-zip-rust/)
## Features
- Supports both ZipCrypto and AES encryption.
- Leverages multiple threads to speed up the process
- Dictionary attack to test passwords from a dictionary text file (one word per line)
- Brute force to generate all passwords for a given charset and a password length range
The available charsets for the password generation are:
```
l | abcdefghijklmnopqrstuvwxyz [a-z]
u | ABCDEFGHIJKLMNOPQRSTUVWXYZ [A-Z]
d | 0123456789 [0-9]
h | 0123456789abcdef [0-9a-f]
H | 0123456789ABCDEF [0-9A-F]
s | «space»!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~
```
Alternatively, you can provide a custom charset file with the `--charsetFile` option.
It accepts a file path for a `txt` file containing a single line of characters to use for the password generation.
## Installation
### Releases
Using the provided binaries in https://github.com/agourlay/zip-password-finder/releases
### Crates.io
Using Cargo via [crates.io](https://crates.io/crates/zip-password-finder).
```bash
cargo install zip-password-finder
```
### AUR
You can install [`zip-password-finder`](https://aur.archlinux.org/packages?O=0&K=zip-password-finder) from the AUR using an [AUR helper](https://wiki.archlinux.org/title/AUR_helpers). For example:
```bash
paru -S zip-password-finder
```
## Usage
```bash
./zip-password-finder -h
Find the password of protected ZIP files
Usage: zip-password-finder [OPTIONS] --inputFile
Options:
-i, --inputFile path to zip input file
-w, --workers number of workers
-p, --passwordDictionary path to a password dictionary file
-c, --charset charset to use to generate password [default: lud]
--charsetFile path to a charset file
--minPasswordLen minimum password length [default: 1]
--maxPasswordLen maximum password length [default: 10]
--fileNumber file number in the zip archive [default: 0]
-h, --help Print help
-V, --version Print version
```
## Performance
For AES make sure to use a CPU with `SHA` instructions (Intel Sandy Bridge or newer, AMD Bulldozer or newer) to get the best performance.
Native builds tend to perform better in general.
```RUSTFLAGS="-C target-cpu=native" cargo build --release```
In general this tool seems to suffer from contention as the number of workers increases which makes it impractical for non-trivial passwords.
It makes sense to use a number of workers equal to the number of physical cores.
E.g. of scalability with an 8 core CPU with 16 threads as the number of workers increases:
