Pre-built binaries

You can download Kryptor for Windows, Linux, and macOS here.

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

Integrity checking

The signatures (.minisign) can be found in each GitHub release. Download the signature for your version and make sure it is in the same directory as the downloaded Kryptor ZIP file.

Downloaded files can be verified with Minisign and the following command:

$ minisign -Vm [filepath] -P RWRZzvSG5htEUFlSEl88cMb0pTGXSZmzqTujwpAweUrSJQuWYui8Qpk9

Minisign should display the message Signature and comment signature verified, followed by the trusted comment Kryptor v[version] Beta.

Running Kryptor on Windows

1. Navigate to the location of the downloaded ZIP file (e.g. the Downloads folder).

2. Right click the kryptor-windows.zip file and select Extract All.

3. Open up the Command Prompt (e.g. search for cmd in the taskbar) and navigate to the path of the extracted folder (e.g. cd C:\Users\USERNAME\Downloads\kryptor-windows).

4. Type kryptor --help for a list of commands and some examples.

When referencing file paths/file names that contain spaces, you must surround them with "speech marks" like so:​

$ kryptor -e -p "GitHub Logo.png"
$ kryptor -e -p "C:\Users\Samuel\Downloads\GitHub Logo.png"

I recommend moving the kryptor.exe and vcruntime140.dll files into C:\Users\USERNAME for easier access from the Command Prompt.

Running Kryptor on Linux & macOS

1. Open up the terminal and navigate to the path of the downloaded ZIP file (e.g. cd Downloads).

2. Type unzip kryptor-linux.zip or unzip kryptor-macos.zipdepending on your version.

3. Navigate into the extracted folder (e.g. cd kryptor-linux).

4. Mark the kryptor file as executable using chmod +x kryptor.

5. Type ./kryptor --help for a list of commands and some examples.

When referencing file paths/file names that contain spaces, you must surround them with 'apostrophes' like so:

$ ./kryptor -e -p 'GitHub Logo.png'
$ ./kryptor -e -p '/home/samuel/Downloads/GitHub Logo.png'

I recommend moving the kryptor file into /home for easier access from the terminal.

Building Kryptor from source

Before you do anything with the source code, make sure you understand the GPLv3 license used by Kryptor. Click here for a summary of GPLv3.​​

Downloading the source code

1. Go to the latest release on GitHub and download Source code (zip).

2. Navigate to the download location and extract the ZIP file.

Using Visual Studio

1. After extracting the soure code ZIP file, navigate to the src/KryptorCLIfolder, and open the KryptorCLI.sln file in Visual Studio 2019 Community.

2. Right click on KryptorCLI in the Solution Explorer and click on Publish... .

3. Choose to publish Kryptor as either win-x64, linux-x64, or osx-x64. Then click Publish. You will find the published executable at the path listed next to Target location.

Note that the libsodium library requires the Visual C++ Redistributable for Visual Studio 2015-2019 to work on Windows. Therefore, you must keep the vcruntime140.dll file in the same folder as kryptor.exe on Windows.​

Using the .NET CLI

1. Install the .NET 5 SDK.

2. From the root folder, copy and paste the following command for the operating system you would like to build for:

Windows (x64)

$ dotnet publish src -c Release -r win-x64 -p:PublishSingleFile=true -p:PublishTrimmed=true -p:IncludeNativeLibrariesForSelfExtract=true --self-contained true 

Linux (x64)

$ dotnet publish src -c Release -r linux-x64 -p:PublishSingleFile=true -p:PublishTrimmed=true -p:IncludeNativeLibrariesForSelfExtract=true --self-contained true ​

macOS (x64)

$ dotnet publish src -c Release -r osx-x64 -p:PublishSingleFile=true -p:PublishTrimmed=true -p:IncludeNativeLibrariesForSelfExtract=true --self-contained true ​

The output path defaults to [project_file_folder]/bin/[configuration]/[framework]/[runtime]/publish/ .
