A cryptographic hash function is a mathematical algorithm that takes an input (or 'message') and returns a fixed-length string of characters ...

Because hashing algorithms works in one direction, the only way to obtain the corresponding plaintext is to guess, a process that can require large amounts of time and computational resources. The ...

Rainbow tables are password cracking tools with origins dating back to research from the early 1980s. Here's how they work and why they haven't stood the test of time.

That’s where encryption, hashing, and obfuscation come in. This article hopes to clear up some misconception in the industry as to how these technologies work and how they relate to each.

But competition entrants face another major challenge. While encryption algorithms rely on keeping a “key” secret from attackers, cryptographic hash functions can have no such secrets.

Researchers say the SHA-1 hashing algorithm, still used to sign almost one in three SSL certificates, should be urgently retired Researchers have found a new way to attack the SHA-1 hashing ...

The National Institute of Standards and Technology retired one of the first widely used cryptographic algorithms, citing vulnerabilities that make further use inadvisable, Thursday. NIST recommended ...
