module: letsencrypt
author: "Michael Gruener (@mgruener)"
version_added: "2.2"
short_description: Create SSL certificates with Let's Encrypt
description:
- "Create and renew SSL certificates with Let's Encrypt. Lets Encrypt is a
free, automated, and open certificate authority (CA), run for the
publics benefit. For details see U(https://letsencrypt.org). The current
implementation supports the http-01, tls-sni-02 and dns-01 challenges."
- "To use this module, it has to be executed at least twice. Either as two
different tasks in the same run or during multiple runs."
- "Between these two tasks you have to fulfill the required steps for the
choosen challenge by whatever means necessary. For http-01 that means
creating the necessary challenge file on the destination webserver. For
dns-01 the necessary dns record has to be created. tls-sni-02 requires
you to create a SSL certificate with the appropriate subjectAlternativeNames.
It is I(not) the responsibility of this module to perform these steps."
- "For details on how to fulfill these challenges, you might have to read through
U(https://tools.ietf.org/html/draft-ietf-acme-acme-02#section-7)"
- "Although the defaults are choosen so that the module can be used with
the Let's Encrypt CA, the module can be used with any service using the ACME
protocol."

description:
- "File containing the CSR for the new certificate."
- "Can be created with C(openssl csr ...)."
- "The CSR may contain multiple Subject Alternate Names, but each one
will lead to an individual challenge that must be fulfilled for the
CSR to be signed."

- "The data to validate ongoing challenges."

of this module."
