Getting Started

1. Install

Linux

wget -qO ~/bin/convey https://get.convey.sh/linux
chmod +x ~/bin/convey
~/bin/convey -h

macOS

curl -sLo ~/bin/convey https://get.convey.sh/macos
chmod +x ~/bin/convey
~/bin/convey -h

Windows

Invoke-WebRequest https://get.convey.sh/windows -OutFile convey.exe
.\convey.exe -h

2. First Use

Configure a keyfile. This can be a local filepath or accessible URL.

convey configure --keyfile FILE

echo "Hello world" | convey
<ID>

convey <ID>
Hello world

The keyfile should be a secret file that can be easily accessed on the machines you want to use convey with.
Your keyfiles don't leave your machine. We create a fingerprint from this file and use that fingerprint only.
Some examples are:

• a text file (e.g. ~/.ssh/id_rsa.pub)
• an image file
• a file with randomly generated bytes - how to
• raw URL to gist - GitHub gist

Configuration

Set configuration with the convey configure command.

Usage:
  convey configure [flags]

Flags:
      --keyfile string        URL or local path to keyfile (at least 64 bytes is required)

      --overwrite             Overwrite current configuration
      --fingerprint string    (advanced) If you know the fingerprint you want to use (SHAKE-256 hex), you can set it directly instead of using --keyfile
      --nats-cacert string    (advanced) Local path to CA certificate used by NATS server
      --nats-cluster string   (advanced) NATS cluster id
      --nats-url string       (advanced) NATS server url

Self-hosting

For convenience, we've provided a hosted service that convey uses by default.
This hosted service uses TLS to ensure communications are encrypted.

Alternatively, you can host your own NATS Streaming Server and configure convey to use that server.
