Zanzibar

Zanzibar is a utility to retrieve secrets from a Secret Server installation. It supports retrieval of a password, public/private key, or secret attachment.

Installation

Add this line to your application's Gemfile:

gem 'zanzibar'

And then execute:

$ bundle

Or install it yourself as:

$ gem install zanzibar

Usage

In your ruby project, rakefile, etc., create a new Zanzibar object.

The constructor takes a hash of optional parameters for the WSDL location, the domain of the Secret Server, a hash of global variables to pass to savon (necessary for windows environments with self-signed certs) and a password for the current user (intended to be passed in through some encryption method, unless you really want a plaintext password there).

All of these parameters are optional and the user will be prompted to enter them if they are missing.

  my_object = Zanzibar::Zanzibar.new(:domain => 'my.domain.net', :wsdl => 'my.scrt.srvr.com/webservices/sswebservice.asmx?wdsl', :pwd => get_encrypted_password_from_somewhere)

Example:

require 'zanzibar'

## Constructor takes hash as argument, all optional :domain, :wsdl, :pwd, :globals
secrets = Zanzibar::Zanzibar.new(:domain => 'mydomain.net', :wsdl => "https://my.scrt.server/webservices/sswebservice.asmx?wsdl")
# On windows with self-signed certs,
# Zanzibar::Zanzibar.new(:domain => 'mydomain.net', :wsdl => "https://my.scrt.server/webservices/sswebservice.asmx?wsdl", :globals => {:ssl_verify_mode => :none})

## Simple password -> takes secret id as argument
secrets.get_password(1234)

## Private Key -> takes hash as argument, requires :scrt_id, :type, optional :scrt_item_id, :path
secrets.download_secret_file(:scrt_id => 2345, :path => 'secrets/', :type => "Private Key")

## Public Key -> takes hash as argument, requires :scrt_id, :type, optional :scrt_item_id, :path
secrets.download_secret_file(:scrt_id => 2345, :path => 'secrets/', :type => "Public Key")

## Attachment; only supports secrets with single attachment -> takes hash as argument, requires :scrt_id, :path, optional :scrt_item_id, :path
secrets.download_secret_file(:scrt_id => 2345, :path => 'secrets/', :type => "Attachment")

Providing Credentials

Zanzibar has several ways of finding Secret Server credentials. It will use credentials discovered in this order:

• Credentials passed to the initializer
  • Zanzibar::Zanzibar.new(:username=>'auser', :password=>'itsmyPassword')
• Credentials discovered via the environment
  • If ZANZIBAR_USER exists, it will use that.
    • If not, it will try USER
  • If ZANZIBAR_PASSWORD exists, it will use that.
• Credentials entered by the user
  • Zanzibar will prompt the user to enter their password on STDIN

Command Line

Zanzibar comes bundled with the zanzibar command-line utility that can be used for fetching passwords and downloading keys from outside of Ruby scripts.

zanzibar supports most actions provided by Zanzibar itself. Because it operates on the command-line, it can be used as part of a pipeline or within a bash script.

# if ZANZIBAR_PASSWORD is not set, you will be prompted to enter your password.
# this will download the private key from secret 1984 to the current directory
$ ZANZIBAR_PASSWORD=`gpg -d secretpasswd.txt.gpg` zanzibar get 1984 -s server.example.com -d example.com -f "Private Key"

$ ssh user@someremote -i ./private_key

Zanzifiles

The zanzibar command can also perform bundler-like actions. Running zanzibar init will generate a Zanzifile in the current directory. Information about Secret Server and the necessary secret files to be downloaded can be added here.

Then zanzibar bundle will try to download the secrets named in the file. When it downloads a file, it gets added to Zanzifile.resolved. And next time zanzibar bundle is run, if the file exists and the hash matches the one in the resolved file, it will not attempt to re-download. zanzibar update will attempt to re-download all secrets.

Subdirectories under the root directory secret_dir can be created for individual keys by specifying a prefix path for that secret. Secrets will default to be downloaded to the root secret_dir directory otherwise.

Note: zanzibar get can fetch passwords or files, but zanzibar bundle can only operate on secret files.

Sample Zanzifile:

---
settings:
  wsdl: my.scrt.srvr.com/webservices/sswebservice.asmx?wsdl
  domain: my.domain.net
  secret_dir: secrets/
  ignore_ssl: true
secrets:
  ssh_key:
    id: 249
    label: Private Key
    prefix: ssh/
  encryption_key:
    id: 483
    label: Attachment
  cert_pem:
    id: 123
    label: Certificate
  cert_key:
    id: 986
    label: Misc Attachment
