        | Sewer is a Let's Encrypt(ACME) client.
        | It's name is derived from Kenyan hip hop artiste, Kitu Sewer.
        | It allows you to obtain ssl/tls certificates from Let's Encrypt.
        
            Let’s Encrypt is a free, automated, and open Certificate Authority.
            - https://letsencrypt.org
        
        | Sewer currently only supports the DNS mode of validation, I have no
          plans of supporting other modes of validation.
        | The currently supported DNS providers are:
        | 1. `Cloudflare <https://www.cloudflare.com/dns>`__
        | 2. `Aurora <https://www.pcextreme.com/aurora/dns>`__
        | 3. `acme-dns <https://github.com/joohoi/acme-dns>`__ 4.
          `Aliyun <https://help.aliyun.com/document_detail/29739.html>`__ 5. `He
          DNS, Hurricane Electric DNS <https://dns.he.net/>`__ 6.
          `Rackspace <https://www.rackspace.com/cloud/dns>`__ 7.
          `DNSPod <https://www.dnspod.cn/>`__ 8.
          `DuckDNS <https://www.duckdns.org/>`__ 9.
          `ClouDNS <https://www.cloudns.net>`__ 10. `AWS
          rout353 <https://aws.amazon.com/route53/>`__ 11. `Bring your own dns
          provider <#bring-your-own-dns-provider>`__ ...
        
        | Sewer can be used very easliy programmatically as a library from code.
        | Sewer also comes with a command-line(cli) interface(app) that you can
          use from your favourite terminal

        unsupported) python2 version, run;

            pip install sewer==0.3.0
        
        | Sewer is in active development and it's API may change in backward
          incompatible ways.

        Usage
        -----

            # 1. to create a new certificate:
            client = sewer.Client(domain_name='example.com',
                                  dns_class=dns_class)
            certificate = client.cert()
            certificate_key = client.certificate_key
            account_key = client.account_key
        
            print("your certificate is:", certificate)
            print("your certificate's key is:", certificate_key)
            print("your letsencrypt.org account key is:", account_key)
            # NB: your certificate_key and account_key should be SECRET.
            # keep them very safe.
        
            # you can write these out to individual files, eg::
        
            with open('certificate.crt', 'w') as certificate_file:
                certificate_file.write(certificate)

                account_key_file.write(account_key)
        
        
            # 2. to renew a certificate:

            dns_class = sewer.CloudFlareDns(CLOUDFLARE_EMAIL='example@example.com',

            # 3. You can also request/renew wildcard certificates:
            import sewer
            dns_class = sewer.CloudFlareDns(CLOUDFLARE_EMAIL='example@example.com',
                                            CLOUDFLARE_API_KEY='nsa-grade-api-key')
            client = sewer.Client(domain_name='*.example.com',
                                  dns_class=dns_class)
            certificate = client.cert()
            certificate_key = client.certificate_key
            account_key = client.account_key
        
        CLI
        ---
        
        | Sewer also ships with a commandline interface(called ``sewer`` or
          ``sewer-cli``) that you can use to get/renew certificates.
        | Your dns providers credentials need to be supplied as environment
          variables.
        
        To get certificate, run:
        
        .. code:: shell
        
            CLOUDFLARE_EMAIL=example@example.com \
            CLOUDFLARE_API_KEY=api-key \
            sewer \
            --dns cloudflare \
            --domain example.com \
            --action run
        
        To renew a certificate, run:
        
        .. code:: shell
        
            CLOUDFLARE_EMAIL=example@example.com \
            CLOUDFLARE_API_KEY=api-key \
            sewer \
            --account_key /path/to/your/account.key \
            --dns cloudflare \

        directory that you run sewer from.
        
        The commandline interface(app) is called ``sewer`` or alternatively you

        Bring your own DNS provider
        ---------------------------
        
        | It is very easy to use any dns provider with sewer.
        | All you have to do is create your own dns class that is a child class
          of
          ```sewer.BaseDns`` <https://github.com/komuw/sewer/blob/master/sewer/dns_providers/common.py>`__
          and then implement the
        | ``create_dns_record`` and ``delete_dns_record`` methods.
        | As an example, if you wanted to use `AWS
          route53 <https://aws.amazon.com/route53/>`__ as your dns provider with
          sewer, you
        | would do something like;
        
        .. code:: python
        
            import sewer
            import boto3
        
        
            class AWSroute53Dns(sewer.BaseDns):

        FAQ
        ---
        
        -  Why another ACME client?
           I wanted an ACME client that I could use to programmatically(as a
           library) acquire/get certificates. However I could not find anything
           satisfactory for use in Python code.
        -  Why is it called Sewer? I really like the Kenyan hip hop artiste
           going by the name of Kitu Sewer.
        
        Here's the ouput of running sewer using the cli app:
        
        .. code:: shell
        
            CLOUDFLARE_EMAIL=example@example.com \
            CLOUDFLARE_API_KEY=nsa-grade-api-key \
            sewer \
            --endpoint staging \
            --dns cloudflare \
            --domain subdomain.example.com \
            --action run
