The key, only one-third the length of most commercial encryption keys, took more than 35 million compute hours to break. How safe is “safe”? That’s the question at the heart of research into breaking encryption keys — research that has led a team in France to the most complex encryption algorithm to date. At 240 characters long, the new record bests the old decryption record by 8 characters, though it still falls far short of the complexity of the algorithms used in commercial cryptography today.
