Quick Start

See this example.

You can run it by cloning this repo, changing directory into this directory, and running a go application. See the terminal command below.

git clone github.com/TBD54566975/ssi-sdk.git
cd ssi-sdk/sd-jwt
go run example/main.go

Usage

API Reference

See our official godocs.

Configuration

Configuration is done via dependency injection on the SDJWTSigner struct.

If you want to inject your own implementation of JWT signatures, you can pass it by implementing a struct that satisfies the Signer interface.

If you want to inject your own random number generator, you can pass it by implementation the SaltGenerator interface. We provide a default one which relies on crypto/rand, which you can instantiate by calling NewSaltGenerator.

Building

See the SDK Building section.
