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.
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 was introduced as a dependency to provide helpers that make the default attribute settings (see Attributes) easier to reason about.
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
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.
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
Most often this will be used to generate a secure password for an attribute. In a recipe:
::Chef::Recipe.send(:include, Chef::OpenSSL::Password) node.set_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:
This cookbook includes an LWRP for generating Self Signed Certificates
generate a pem formatted x509 cert + key
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"
openssl_x509 "/tmp/mycert.pem" do common_name "www.f00bar.com" org "Foo Bar" org_unit "Lab" country "US" end

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!).
