The Electronic Frontier Foundation has released an interesting comparison chart showing how well the most common instant messaging platforms compete on security.

The EFF analysis looked at these criteria:

  • Encrypted in transit
  • Encrypted so the provider can't read it
  • Can you verify contacts identity
  • Are past communication protected if keys are stolen 
  • Is the code open to independent review
  • Is security design properly documented
  • Has the code been audited
    Are

The highest rated tools (scoring 7 out of 7) were:

  • ChatSecure
  • CryptoCat
  • Signal/Redphone
  • Silent Phone
  • Silent Text
  • TextSecure

Not surprisingly, Apple's Facetime & iMessage (Messages) were ranked as the most secure mass market messaging tools. 

although neither currently provides complete protection against sophisticated, targeted forms of surveillance
— EFF

Google Hangouts, Facebook Messenger, Blackberry Messenger and Microsoft's Skype were dinged on several fronts including lack of protection of past communications and lack of detailed documentation about security.
