Cross-platform Python client for ARX CoSign electronic signatures via SOAP API
Summary
Revenant is a cross-platform client for the discontinued DocuSign Signature Appliance (formerly ARX CoSign) electronic signature system, specifically built to work with the Armenian Government's EKENG CoSign appliance. It provides both Python and TypeScript libraries, as well as desktop applications for macOS, Linux, and Windows, enabling PDF signing via the legacy SOAP API. The project is well-maintained with comprehensive documentation, CI/CD, multiple distribution channels, and addresses a real-world need despite the underlying technology being officially retired.
