Minisign
========

Minisign is a dead simple tool to sign files and verify signatures.

For more information, please refer to the
[Minisign documentation](https://jedisct1.github.io/minisign/)

Tarballs and pre-compiled binaries can be verified with the following
public key:

    RWQf6LRCGA9i53mlYecO4IzT51TGPpvWucNSCh1CBM0QTaLn73Y7GFO3

Compilation / installation
--------------------------

## Using [Zig](https://ziglang.org):

Dependencies:

* [libsodium](https://libsodium.org/)

Compilation:

    $ zig build -Drelease-safe

## Using cmake and gcc or clang:

* [libsodium](https://libsodium.org/)
* cmake
* pkg-config
* gcc or clang

Compilation:

    $ mkdir build
    $ cd build
    $ cmake ..
    $ make
    # make install

Alternative configuration for static binaries:

    $ cmake -D STATIC_LIBSODIUM=1 ..

or:

    $ cmake -D BUILD_STATIC_EXECUTABLES=1 ..

Minisign is also available in Homebrew:

    $ brew install minisign

Minisign is also available in Scoop on Windows:

    $ scoop install minisign

Minisign is also available in chocolatey on Windows:

    $ choco install minisign

Minisign is also available with docker:

    $ docker run -i --rm jedisct1/minisign

The image can be verified with the following cosign public key:

Additional tools, libraries and implementations
-----------------------------------------------

* [minizign](https://github.com/jedisct1/zig-minisign) is a compact
implementation in Zig, that can also use ssh-encoded keys.
* [minisign-misc](https://github.com/JayBrown/minisign-misc) is a very
nice set of workflows and scripts for macOS to verify and sign files
with minisign.
* [go-minisign](https://github.com/jedisct1/go-minisign) is a small module
in Go to verify Minisign signatures.
* [rust-minisign](https://github.com/jedisct1/rust-minisign) is a Minisign
library written in pure Rust, that can be embedded in other applications.
* [rsign2](https://github.com/jedisct1/rsign2) is a reimplementation of
the command-line tool in Rust.
* [minisign (go)](https://github.com/aead/minisign) is a rewrite of Minisign
in the Go language. It reimplements the CLI but can also be used as a library.
* [minisign-verify](https://github.com/jedisct1/rust-minisign-verify) is
a small Rust crate to verify Minisign signatures.
* [minisign-net](https://github.com/bitbeans/minisign-net) is a .NET library
to handle and create Minisign signatures.
* [minisign](https://github.com/chm-diederichs/minisign) a Javascript
implementation.
* WebAssembly implementations of [rsign2](https://wapm.io/package/jedisct1/rsign2)
and [minisign-cli](https://wapm.io/package/jedisct1/minisign) are available on
WAPM.
* [minisign-php](https://github.com/soatok/minisign-php) is a PHP implementation.
* [py-minisign](https://github.com/x13a/py-minisign) is a Python
implementation.

Signature determinism
---------------------

This implementation uses deterministic signatures, unless libsodium
was compiled with the `ED25519_NONDETERMINISTIC` macro defined. This
adds random noise to the computation of EdDSA nonces.

Other implementations can choose to use non-deterministic signatures
by default. They will remain fully interoperable with implementations
using deterministic signatures.
