qzip3 Compressor

A minimalistic implementation of FrodoKEM lattice encryption layer over a slightly improved Bzip2 compression. Inspired by https://github.com/microsoft/PQCrypto-LWEKE.

Usage

A single file/folder (de)compression / (de)encryption is supported.

# compression 
qzip3 -c inputFile|inputFolder [-p password] -o outputFile

# decompression
qzip3 -d achiveFile [-p password]

Examples

With encryption

# compress the file and encrypt 
qzip3 -c file.txt -p test -o file.qzip3

# decrypt and decompress
qzip3 -d file.qzip3 -p test

Without encryption

Without encryption, a modified Burrows–Wheeler transform is used which can improve compression rate for small (1KB) text files.

# compress
qzip3 -c file -o file.qzip3


# decompress
qzip3 -d file.qzip3

Note

Decompression is done to the folder where the archive file is located. Not to mistakenly pollute the working directory, put the archive file into a separate folder and extract:

# The extracted files will be placed in mydir

qzip3 -d mydir/file.qzip3 

Requirements

Opam v4.1+ is required.

Releases

Binary releases are available for Linux only.
