  @options = {
    :name       => {},                #required, CertificateName
    :key        => nil,               #required

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method) ⇒ Object

This method is used to intercept and pass-thru calls to openSSL methods and instance variables.
