You have intercepted an encrypted English text message. You know who sent it and the intended recipient they were sending it to, but do not know the exact content, the encryption mechanism or any other factors.

b) For automated techniques estimate approximately how long the technique would take to decipher the message on current high end consumer hardware (AMD Ryzen Threadripper3990X running at 4.35GHz).For manual processes you need to estimate the likelihood of success/effectiveness. You may need to make educated assumptions about aspects of the encrypted message and any manual processes. These must be researched online (identify the source of your assumption/information) and must be clearly explained.
