README

signit

A tool to help you sign and verify signatures of messages using your ed25519 ssh keys.

If you add your ed25519 public key to your github account, anyone can verify your messages without giving them your public key manually!

Prerequisite: Generating an ed25519 SSH Key

Run the following command, and follow the instructions. You don't need to do this if you already have an ed25519 ssh key.

ssh-keygen -t ed25519

Round Trip Example

This uses my $HOME/.ssh/id_ed25519 key to sign, and my public keys on github to verify.

signit sign -p -m "Hello, world" -g jamesmunns | tee msg.json | signit verify -g && cat ./msg.json

Verified!
{
  "message": "Hello, world",
  "signature": "JruolFnpOE6uQy0gqSE2VfrHPYr2De7cDdiIOAhDLIkIN5MmK+oT4HRNpB2Y0QSY1XGVMODHG1fWOeFwdl+YDg==",
  "github_user": "jamesmunns"
}
