Among other desirable properties of hash functions, an interesting one is that it should be collision-resistant, that is it should be difficult to find two messages with the same hash value.

The SHA-1 hashing algorithm, still used to sign almost one in three SSL certificates, can now be attacked for as little as $75,000, and should be urgently retired, researchers say ...

Their integration into diverse applications—from network security to big data processing—has catalysed innovative approaches in managing the immense data streams prevalent in modern computing ...
