Introduction

Kryptor is free and open source file encryption software for Windows,
Linux, and macOS.

It is a portable, cross-platform command line tool that makes use of
modern and secure cryptographic algorithms. It aims to be a mixture
of age and Minisign in order to provide a simple, user friendly
alternative to GPG.

Download Kryptor 

The latest version is v3.0.3. Here are the pre-built binaries:

  *  Windows (x64) (Minisign signature)

  *  Linux (x64) (Minisign signature)

  *  macOS (x64) (Minisign signature)

For instructions on verifying the signatures, please see the 
Installation page.

Please follow the project on GitHub and regularly use the -u|--update
option to check for updates. It is important to stay up-to-date for
security and compatibility reasons. 

Source code 

You can find the source code on GitHub.

Goals 

  * Secure, modern, and fast cryptographic algorithms.

  * Chunked AEAD stream encryption.

  * No cryptographic agility.

  * Support for passwords, keyfiles, and asymmetric keys.

  * Support for file and directory encryption, meaning you can
    encrypt multiple files at once.

  *  Authenticated key exchange for hybrid file encryption.

  * Support for file signing so you do not have to use separate tools
    for encryption and signing. 

  * Short, copy/pasteable public keys. Shareable public key files.

  * Private key encryption for protection at rest. 

  * Optional file/directory name obfuscation.

  * Keep it simple, stupid! Avoid unnecessary complexity and too many
    features.

The goal is for Kryptor to be a mixture of age and Minisign, whilst
tweaking some design decisions and remaining simple/user friendly.
This means symmetric and hybrid file encryption as well as file
signing are in scope.

Kryptor is primarily designed to protect files for cloud backups,
external storage backups, and file sharing. It is by no means a 
complete replacement for GPG, but that is a good thing considering
the sheer number of features is what makes GPG difficult to use for
many tasks.
