Signare focuses on delivering an enterprise-grade digital signing solution for Ethereum clients. The application consists of a REST API server to manage resource configuration and an ETH-JSON 2.0 server to provide functionality for the use of generating, removing, listing and signing Ethereum transactions. The objective of Signare is to provide a FIPS 140-2 Level 2 compliant signing solution for enterprise applications. Signare is built from the ground up to provide signing solutions for organizations that need: Enterprise grade software  Can integrate into the organization’s Authentication Service Can run in High Availability environments Has mature Roles Based Access Control (RBAC) Keys stored in Hardware Secure Modules (HSMs) or HSM backed cloud services FIPS 140-2 Level 2 compliant PKCS#11 protocol implementation Signare is intended to complement some of the existing Hyperledger projects and has been tested with the following: Hyperledger Besu Harmonia, a Hyperledger Lab The roadmap for Signare includes testing with Hyperledger Firefly How to contribute Signare’s documentation includes A getting started guide Full Reference: Documentation  An OpenAPI Specification Role-based access control documentation. Security model information. User guides Configuration guides Using the above documentation, you can get started with Signare, and you can deploy and test the software using the test suite that is provided in the repository. Once you are comfortable with the product, we would encourage you to contribute to the project and we’ve created the following in the repository Guidelines for contributing. Standards for writing code. Guide of the standards of how to document the code. Guide for integrating with a new HSM. Guidelines for creating pull requests. We look forward to hearing from you.
