Introduction

Libreswan Opportunistic IPsec using LetsEncrypt is a project created during Google Summer of Code 2019. It adds a utility letsencrypt to the ipsec. letsencrypt invokes any of several utilities involved in controlling the Opportunistic Encryption system, running the specified {command} with the specified [argument] as if it had been invoked directly.

e.g. ipsec letsencrypt -h lists the available commands.

It is a program in libreswan, which integrates libreswan with Opportunistic Encryption utilities. The script provides various OE functionality e.g. initial OE setup, testing configuration/connection, generating and updating Let's Encrypt certificates. The details about the utilities and using them can be found in the Documentation: Libreswan Opportunistic IPsec using LetsEncrypt . Also, the documentation includes the sample output for each {command} and [argument].

Implementation

Various functionalities of the project are listed below:

  • Can establish the secure OE (Opportunistic Encryption) connections between two hosts (client and server).
  • Checks for the success in establishing the OE connection.
  • Easy to install on the hosts (client and server).
  • Can test OE connections between two hosts.
  • Checks if certbot is installed (on the server).
  • Can generate Let's Encrypt certificates for the server using certbot.
  • Generates the certbot configuration for reusing the private key.
  • Enables automatic update of the generated certificates, keeping the private key same.
  • Generates the #pkcs12 file.
  • Imports the generated certificates into NSS Database to be used for OE.
  • Downloads the LetsEncrypt CA and intermediate certificates.
  • Saves the default client/server configuration.
  • Displays OE connection status to the user.
  • Displays the certificates installed in NSS database.
  • Provides details about various available utilities, {commands} and [arguments].
