openssl Cookbook
|
|
================
|
|
|
|
This cookbook provides a library method to generate secure random passwords in recipes using the Ruby OpenSSL library.
|
|
|
|
It also provides an attribute-driven recipe for upgrading OpenSSL packages.
|
|
|
|
Requirements
|
|
------------
|
|
|
|
The `secure_password` works on any platform with OpenSSL Ruby bindings installed, which are a requirement for Chef anyway.
|
|
|
|
The upgrade recipe works on the following tested platforms:
|
|
|
|
* Ubuntu 12.04, 14.04
|
|
* Debian 7.4
|
|
* CentOS 6.5
|
|
|
|
It may work on other platforms or versions of the above platforms with or without modification.
|
|
|
|
[Chef Sugar](https://github.com/sethvargo/chef-sugar) was introduced as a dependency to provide helpers that make the default attribute settings (see Attributes) easier to reason about.
|
|
|
|
Attributes
|
|
----------
|
|
|
|
* `node['openssl']['packages']` - An array of packages of openssl. The default attributes attempt to be smart about which packages are the default, but this may need to be changed by users of the `openssl::upgrade` recipe.
|
|
* `node['openssl']['restart_services']` - An array of service resources that use the `node['openssl']['packages']`. This is empty by default as Chef has no reliably reasonable way to detect which applications or services are compiled against these packages. *Note* These each need to be "`service`" resources specified somewhere in the recipes in the node's run list.
|
|
|
|
Recipes
|
|
-------
|
|
|
|
### upgrade
|
|
|
|
The upgrade recipe iterates over the list of packages in the `node['openssl']['packages']` attribute and manages them with the `:upgrade` action. Each package will send `:restart` notification to service resources named by the `node['openssl']['restart_services']` attribute.
|
|
|
|
Usage
|
|
-----
|
|
|
|
Most often this will be used to generate a secure password for an attribute. In a recipe:
|
|
|
|
```ruby
|
|
::Chef::Recipe.send(:include, Opscode::OpenSSL::Password)
|
|
node.default_unless[:my_password] = secure_password
|
|
```
|
|
|
|
To use the `openssl::upgrade` recipe, set the attributes as mentioned above. For example, we have a "stats_collector" service that uses openssl. It has a recipe that looks like this:
|
|
|
|
LWRP
|
|
====
|
|
|
|
This cookbook includes an LWRP for generating Self Signed Certificates
|
|
|
|
## openssl_x509
|
|
generate a pem formatted x509 cert + key
|
|
|
|
### Attributes
|
|
`common_name` A String representing the `CN` ssl field
|
|
`org` A String representing the `O` ssl field
|
|
`org_unit` A String representing the `OU` ssl field
|
|
`country` A String representing the `C` ssl field
|
|
`expire` A Fixnum reprenting the number of days from _now_ to expire the cert
|
|
`key_file` Optional A string to the key file to use. If no key is present it will generate and store one.
|
|
`key_pass` A String that is the key's passphrase
|
|
`key_length` A Fixnum reprenting your desired Bit Length _Default: 2048_
|
|
`owner` The owner of the files _Default: "root"_
|
|
`group` The group of the files _Default: "root"_
|
|
`mode` The mode to store the files in _Default: "0400"_
|
|
|
|
### Example usage
|
|
|
|
openssl_x509 "/tmp/mycert.pem" do
|
|
common_name "www.f00bar.com"
|
|
org "Foo Bar"
|
|
org_unit "Lab"
|
|
country "US"
|
|
end
|

=======
|
|
|
|
|
|
```ruby
|
|
node.default['openssl']['restart_services'] = ['stats_collector']
|
|
|
|
# other recipe code here...
|
|
service 'stats_collector' do
|
|
action [:enable, :start]
|
|
end
|
|
|
|
include_recipe 'openssl::upgrade'
|
|
```
|
|
|
|
This will ensure that openssl is upgraded to the latest version so the `stats_collector` service won't be exploited (hopefully!).
