# File 'lib/metasploit/credential/creation.rb', line 12 def active_db? ActiveRecord::Base.connected? end |
#create_cracked_credential(opts = {}) ⇒ Object
This method takes a few simple parameters and creates a new username/password credential that was obtained by cracking a hash. It reuses the relevant components form the originating Metasploit::Credential::Core and builds new Login objects based on the ones attached to the originating Metasploit::Credential::Core

#invalidate_login(opts = {}) ⇒ void
This method returns an undefined value.
This method checks to see if a Login exists for a given set of details. If it does exists, we then appropriately set the status to one of our failure statuses.
