Secure Hash Algorithm 1 (SHA-1), a cryptographic hash function used for producing hash “digests” (each 40 hexadecimal characters long), can be considered a good algorithm.

Researchers have found a new way to attack the SHA-1 hashing algorithm, still used to sign almost one in three SSL certificates that secure major websites, making it more urgent than ever to ...

Perhaps most importantly, Keccak operates completely unlike the SHA-2 algorithms, meaning that any work that has been done to compromise SHA-2 would not apply to SHA-3, Polk said.

So, an algorithm is the process a computer uses to transform input data into output data. A simple concept, and yet every piece of technology that you touch involves many algorithms.

Most of the major web browsers will end support for the SHA-1 hashing algorithm by February of next year because the algorithm is becoming outdated.

Perhaps most importantly, Keccak operates completely unlike the SHA-2 algorithms, meaning that any work that has been done to compromise SHA-2 would not apply to SHA-3, Polk said. “Classes of ...
