rbcl

Go library that bundles libsodium and provides wrappers for its Ristretto group functions. This library is based on the python implementation of the same.

installation and usage

This library is available via go get:

go get github.com/bengetch/rbcl

And can be imported in the usual way:

import (
	"github.com/bengetch/rbcl"
)

This library exports Go wrappers for constructors, point arithmetic functions, and scalar arithmetic functions. Some usage examples are presented below:

import (
	"github.com/bengetch/rbcl"
)

p := CryptoCoreRistretto255Random()
v := CryptoCoreRistretto255IsValidPoint(p) // true

t := CryptoCoreRistretto255Random()
pt, err := CryptoCoreRistretto255Add(p, t)
tp, err := CryptoCoreRistretto255Add(t, p)
e1 := pt == tp // true

s := CryptoCoreRistretto255ScalarRandom()
r := CryptoCoreRistretto255ScalarRandom()

sr, err := CryptoCoreRistretto255ScalarMul(s, r)
rs, err := CryptoCoreRistretto255ScalarMul(r, s)
e2 := sr == rs // true

Further examples can be seen in the test files.

development

Development of this library requires libsodium source code, a pinned version of which is included in this repo as a submodule. Before developing features on a branch, then, ensure that you've pulled libsodium correctly via:

git clone https://github.com/bengetch/rbcl.git
cd rbcl
git submodule update --init --recursive

If you have already cloned this repository, and the libsodium distribution inside of it has been updated:

git submodule update --recursive --remote

testing

Tests can be executed in the normal way:

go test .

As well as linting:

golangci-lint run .

todo

Need to extend the release.yml actions file to test and lint source code before pushing a new version.
