Blockstack SSH Key retriever

Blockstack is a decentralized identity provider. It allows users to attach an SSH key to their public profile in a cryptographically-verifiable way. Using the public Blockstack API, it's possible to retrieve that profile and extract the SSH key from it in a format that enables a direct-to-authorized_keys pipeline:

blockstack-sshkey colindean.id >> ~/.ssh/authorized_keys

Configuration

By default, the endpoint used is https://core.blockstack.org. To use a different endpoint, set the ENDPOINT environment variable. See src/retrieve.rs for URLs used.

Installation

Homebrew is the supported method of installing binaries.

Tap and install with:

brew tap colindean/blockstack-sshkey https://github.com/colindean/blockstack-sshkey.git
brew install blockstack-sshkey-bin

Alternatively, download the latest release here.

For Windows, you can use the MSVC version if you already have the 2015 Visual C++ Runtime already installed. Otherwise, try the GNU version.
