Google just cracked one of the building blocks of web encryption (but don’t worry)

Today, Google made major waves in the cryptography world, announcing a public collision in the SHA-1 algorithm. It’s a deathblow to what was once one of the most popular algorithms in cryptography, and a crisis for anyone still using the function. The good news is, almost no one is still using SHA-1, so you don’t need to rush out and install any patches. But today’s announcement is still a major power play from Google, with real implications for web security overall.
