rsa-server

A simple server for storing and verifying public keys.

Usage

First, run npm install to install the dependencies.

Server

To start the server, run node server.js. It can be configured with environment variables:

• PORT: The port to listen on. Defaults to 4545.
• USERNAME: The username to use for the server. Defaults to zachary.
• PASSWORD: The password to use for the server. Defaults to password.

Example:

PORT=4546 USERNAME=zachary PASSWORD=password node server.js

Client

To start the client, run node client.js. It can be configured with environment variables:

• PORT: The port to connect to. This should match the port used to launch the server.Defaults to 4545.
• USERNAME: The username to use for the client. Defaults to zachary.
• PASSWORD: The password to use for the client. Defaults to password.

Example:

PORT=4546 USERNAME=zachary PASSWORD=password node client.js

Initially you will need to create a keypair:

$ node client.js create

You can then publish the public key to the server. The server will update its database with the public key for the logged in user.

$ node client.js publish

You can then sign a message:

$ node ./client.js sign -m "Message"

And finally, you can verify a signature:

$ node client.js verify -m "Message" -s "<signature>"

  The message was signed by this signature.
