This is EnvKey's cross-platform native application. It supports Mac, Windows, and Linux.
EnvKey is an end-to-end encrypted secrets and configuration management tool. It keeps your configuration securely and automatically in sync for all your developers and servers.
The EnvKey App enforces a zero-knowledge protocol. The server never sees configuration in plain text, and never sees encryption passphrases.
