There are cases where more than one version of python2 is installed, and where the default is not 2.7. For example in CentOS 6, it is common for both 2.6 and 2.7 to be installed, as yum requires 2.6 apparently for some reason.
.. notice for github users Disclaimer ========== This is a **DEVELOPER PREVIEW** intended for developers and testers only. **DO NOT RUN THIS CODE ON A PRODUCTION SERVER. IT WILL INSTALL CERTIFICATES SIGNED BY A TEST CA, AND WILL CAUSE CERT WARNINGS FOR USERS.** Browser-trusted certificates will be available in the coming months. For more information regarding the status of the project, please see https://letsencrypt.org.

About the Let's Encrypt Client ============================== |build-status| |coverage| |docs| |container| In short: getting and installing SSL/TLS certificates made easy (`watch demo video`_). The Let's Encrypt Client is a tool to automatically receive and install X.509 certificates to enable TLS on servers. The client will interoperate with the Let's Encrypt CA which will be issuing browser-trusted certificates for free. It's all automated: * The tool will prove domain control to the CA and submit a CSR (Certificate Signing Request). * If domain control has been proven, a certificate will get issued and the tool will automatically install it. All you need to do to sign a single domain is:: user@www:~$ sudo letsencrypt -d www.example.org certonly For multiple domains (SAN) use:: user@www:~$ sudo letsencrypt -d www.example.org -d example.org certonly and if you have a compatible web server (Apache or Nginx), Let's Encrypt can not only get a new certificate, but also deploy it and configure your server automatically!:: user@www:~$ sudo letsencrypt -d www.example.org run **Encrypt ALL the things!** .. |build-status| image:: https://travis-ci.org/letsencrypt/letsencrypt.svg?branch=master :target: https://travis-ci.org/letsencrypt/letsencrypt :alt: Travis CI status .. |coverage| image:: https://coveralls.io/repos/letsencrypt/letsencrypt/badge.svg?branch=master :target: https://coveralls.io/r/letsencrypt/letsencrypt :alt: Coverage status .. |docs| image:: https://readthedocs.org/projects/letsencrypt/badge/ :target: https://readthedocs.org/projects/letsencrypt/ :alt: Documentation status .. |container| image:: https://quay.io/repository/letsencrypt/letsencrypt/status :target: https://quay.io/repository/letsencrypt/letsencrypt :alt: Docker Repository on Quay.io .. _`installation instructions`: https://letsencrypt.readthedocs.org/en/latest/using.html .. _watch demo video: https://www.youtube.com/watch?v=Gas_sSB-5SU Current Features ---------------- * Supports multiple web servers: - apache/2.x (tested and working on Ubuntu Linux) - nginx/0.8.48+ (under development) - standalone (runs its own simple webserver to prove you control a domain) * The private key is generated locally on your system. * Can talk to the Let's Encrypt (demo) CA or optionally to other ACME compliant services. * Can get domain-validated (DV) certificates. * Can revoke certificates. * Adjustable RSA key bit-length (2048 (default), 4096, ...). * Can optionally install a http -> https redirect, so your site effectively runs https only (Apache only) * Fully automated. * Configuration changes are logged and can be reverted. * Text and ncurses UI. * Free and Open Source Software, made with Python.
