Commentary

Context: "What is your 'safe' word?"

I could tell you.

But it's encrypted using a polyalphabetic cipher, and I change the key daily.

I will say this: the Enigma machine is the greatest sex toy ever invented.

Every day, your Safe Word of the Day™ might be your CIA activation phrase.

Will this be the day you experience National Security Autoasphyxiation Euphoria?

"Could teach the Honored Matres a thing or 2 about programming!"
