zap's Introduction

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 archive [INPUT] [OUTPUT]

Where the [OUTPUT] is the path to which you want to store the .zap file. Eg:

zap archive /path/to/dir ./dir.zap -ce

Using zap archive --help will list the available options for encryption and compression.

In order to decompress a Zap archive

zap extract [ARCHIVE] [OUTPUT]

Where the [ARCHIVE] is the path to the file which you want to extract and the [OUTPUT] is the folder in which you want the contents to be placed inside.

Using zap archive --help will list the available options for encryption and compression.

zap extract ./dir.zap ./dir -ce

Unfortunately, in it's current state, that compression and encryption methods aren't stored in metadata and must be given when extracting. this will be fixed in coming releases.

In order to list the contents of a Zap archive

zap list [ARCHIVE]

coming soon

zap's Issues

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.)
