Let's make this birthday one to remember.

68 years old (Born on September 15, 1956)

Happy Birthday, Ross! May your celebrations be encrypted with joy and your cake secured against unauthorized forks. From leading groundbreaking cryptography research at Cambridge to crafting the legendary Serpent cipher, you've consistently cracked life's toughest codes—though hopefully not today's birthday candles!

Your contributions to security engineering have inspired countless minds and safeguarded digital worlds. Whether wrestling BEARs or taming LIONs, you've always kept attackers guessing. Here's wishing you another year filled with brilliant breakthroughs, witty lectures, and perhaps fewer cryptographic puzzles (but we doubt you'd prefer that). Cheers to a timeless classic—just like your algorithms!
