Why aren’t we using SHA-3?

Over the last two years, most of the digital world was forced to move from the flawed SHA-1 (Secure Hash Algorithm version 1) digital hash to SHA-2 (Secure Hash Algorithm version 2) because of increasingly successful cipher attacks. Anyone involved in those migrations knows the many hundreds of hours of research and work it took to successfully pull it off with minimal operational interruption. In more cases than we would care to admit, we prepared as best we could, “threw the switch,” and then hoped for the best. Cipher migrations aren’t something I would wish on my worst enemies.
