An extremely fast alternative to zip which is written in rust.

Last update: Dec 23, 2022

Overview

Zap

Compress and/or encrypt folders fast. Like, really fast. or as some say, blazingly fast.

Installation

To install Zap, run the following command from the project root: cargo install --path .

Usage

In order to compress a folder with Zap, run:

zap FOLDER_TO_ZAP PATH_TO_ZAP_FILE

Where the PATH_TO_ZAP_FILE is the path to which you wanna store the .zap file.

The zap file can optionally be encrypted with by providing the -e flag. A keyfile.zk containing the "password" (keys) will be generated in the current folder.

In order to decompress a folder with Zap

zap PATH_TO_ZAP_FILE FOLDER_TO_UNZAP_INTO

Where the PATH_TO_ZAP_FILE is the path to the file which you wanna unzap and the FOLDER_TO_UNZAP_INTO is the folder in which you want the contents to be placed inside.

If the Zap file was encrypted, the -e flag needs to be provided along with the keyfile.zk which was generated upon zapping.

Comments

Added encryption and reworked the Read/Write structs.

The Read/Write structs have been reworked so that one can efficiently add encryption and signing as well as swapping out compression algorithms. Currently, only aes256CBC(password) has been added to encryption and the signing structs is pass-through only.

All-zero IVs

You currently use a static initialisation vector (of all-0). This is insecure.

I don't mean to be too pushy about this, but it may be prudent to replace the OpenSSL dependency with RustCrypto's AEADs where possible, which are considerably more difficult to misuse, and which will also automatically alert on decryption failure due to a wrong encryption key.

(I don't know the specifics of the original zip program this one is modelled after. Apologies if the zero-IV is needed for compatibility, though explaining that in the source file may be helpful in that case.)
