Constellation forms a network of nodes, each of which advertises a list of public keys that they are the recipient for. Each node exposes an API which allows the user to send a payload to one or more public keys. That payload will be encrypted for the public key before being transferred over the wire to the recipient node. You can think of it as a network of Mail Transfer Agents (MTAs) exchanging PGP-encrypted emails.

- First time only: Install Stack:
- Linux:
curl -sSL https://get.haskellstack.org/ | sh- MacOS:brew install haskell-stack - First time only: run
stack setupto install the Haskell compiler - Run
stack install
- To generate a key pair "node", run
constellation-node --generatekeys=node
If you choose to lock the keys with a password, they will be encrypted using a master key derived from the password using Argon2i. This is designed to be a very expensive operation to deter password cracking efforts. When constellation encounters a locked key, it will prompt for a password after which the decrypted key will live in memory until the process ends.
- Run
constellation-node <path to config file>or specify configuration variables as command-line options (seeconstellation-node --help)
For now, please refer to the Constellation client Go library for an example of how to use Constellation. More detailed documentation coming soon!
