~~~~~~~~~~~~~~
This release comes after more than two years and contains many interesting new features and improvements.
In addition to multiple new plugins, such as ACME-http01, ADCS, PowerDNS, UltraDNS, Entrust, SNS, many of Lemur's existing
flows have improved.

- default to 1y validity during rotation for multi-year browser-trusted certs
- Certificate: search_by_name, and important performance improvements
- UI
- reducing the EC curve options to the relevant ones
- edit option for notifications, destinations and sources
- showing 13 month validity as default

Adds support for SNS notifications. SNS notifications (like other notification plugins) are currently only supported

are then combined to build the topic ARN. Lemur must have access to publish messages to the specified SNS topic.

Lemur includes the ability to create Email notifications by **default**. These notifications

determines if a given certificate is eligible for notification. There are currently only two parameters used to
determine if a certificate is eligible; validity expiration (date the certificate is no longer valid) and the number
of days the current date (UTC) is from that expiration date.

OpenSSH
=======
OpenSSH (also known as OpenBSD Secure Shell) is a suite of secure networking utilities based on the Secure Shell (SSH) protocol, which provides a secure channel over an unsecured network in a client–server architecture.
Using a PKI with OpenSSH means you can sign a key for a user and it can log into any server that trust the CA.
Using a CA avoids TOFU or synchronize a list of server public keys to `known_hosts` files.
This is useful when you're managing large number of machines or for an immutable infrastructure.
Add first OpenSSH authority
---------------------------
To start issuing OpenSSH, you need to create an OpenSSH authority. To do this, visit
Authorities -> Create. Set the applicable attributes:
- Name : OpenSSH
- Common Name: example.net
Then click "More Options" and change the plugin value to "OpenSSH".
Just click to "Create" button to add this authority.
.. note:: OpenSSH do not support sub CA feature.
Add a server certificate
-------------------------
Now visit Certificates -> Create to add a server certificate. Set the applicable attributes:
- Common Name: server.example.net
Then click "More Options" and set the Certificate Template to "Server Certificate".
This step is important, a certificat for a server and for a client is not exactly the same thing.
In this case "Common Name" and all Subject Alternate Names with type DNSName will be added in the certificate.
Finally click on "Create" button.
Add a client certificate
------------------------
Now visit Certificates -> Create to add a client certificate. Set the applicable attributes:
- Common Name: example.net
Then click "More Options" and set the Certificate Template to "Client Certificate".
In this case the name of the creator is used as principal (in this documentation we assume that this certificate is created by the user "lemur").
Finally click on "Create" button.
Configure OpenSSH server
------------------------
Connect to the server.example.net server to correctly configure the OpenSSH server with the CA created previously.
First of all add the CA chain, private and public certificates:
- Create file `/etc/ssh/ca.pub` and copy the "CHAIN" content of the *server certificate* (everything in one line).
- Create file `/etc/ssh/ssh_host_key` and copy "PRIVATE KEY" content.
- Create file `/etc/ssh/ssh_host_key.pub` and copy "PUBLIC CERTIFICATE" content (everything in one line).
Set the appropriate right:
.. code-block:: bash
chmod 600 /etc/ssh/ca.pub /etc/ssh/ssh_host_key
chmod 644 /etc/ssh/ssh_host_key.pub
chown root: /etc/ssh/ca.pub /etc/ssh/ssh_host_key /etc/ssh/ssh_host_key.pub
Then change OpenSSH server configuration to use these files. Edit `/etc/ssh/sshd_config` and add::
TrustedUserCAKeys /etc/ssh/ca.pub
HostKey /etc/ssh/ssh_host_key
HostCertificate /etc/ssh/ssh_host_key.pub
You can remove all other `HostKey` lines.
Finally restart OpenSSH.
.. note:: By default the server public certificate is sign for 2 weeks. You must update the `/etc/ssh/ssh_host_key.pub` file before this delay. You can use the config's parameter OPENSSH_VALID_INTERVAL_SERVER to change this behavor (unit is number of day).
Configure the OpenSSH client
----------------------------
Now you can configure the user's computer.
First of all add private and public certificates:
- Create file `~/.ssh/key` and copy "PRIVATE KEY" content.
- Create file `~/.ssh/key.pub` and copy "PUBLIC CERTIFICATE" content of the *client certicate* (everything in one line).
Set the appropriate right:
.. code-block:: bash
chmod 600 ~/.ssh/key.pub ~/.ssh/key
To avoid TOFU, edite the `~/.ssh/known_hosts` file and add a new line (all in one line):
- @cert-authority \*example.net
- the "CHAIN" content
Now you can connect to server with (here 'lemur' is the principal name and must exists on the server):
.. code-block:: bash
ssh lemur@server.example.net -i ~/.ssh/key
With this configuration you don't have any line like::
Warning: Permanently added 'server.example.net,192.168.0.1' (RSA) to the list of known hosts.
And you don't have to enter any password.
.. note:: By default the client public certificate is sign for 1 day. You must update the `.ssh/key.pub` everyday. You can use the config's parameter OPENSSH_VALID_INTERVAL_CLIENT to change this behavor (unit is number of day).
