You can’t un-ring a bell, but you might be able to un-hash an email, depending on whom you ask. In order for marketers to safely use hashes for targeted advertising, they must stay abreast of the ...

Passwords are the keys to our online identities, and as a result, they’re also near the top of the target list for attackers. There have been countless breaches in the last few years in which ...

The National Institute of Standards and Technology (NIST) this week opened a competition to develop a new cryptographic hash algorithm, a tool that converts a file, message or block of data to a short ...

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 retire it ...

Hashing is a one-way cryptographic function while encryption is designed to work both ways. Encryption algorithms take input and a secret key and generate a random looking output called a ciphertext.

The design of cryptographic hash functions is crucial for ensuring the security of digital information. In this context, cellular automata (CAs) have emerged as a promising tool due to their inherent ...

Over the past several months, we've seen major breaches exposing numerous usernames and passwords. The eBay and Adobe breaches impacted millions of accounts. Snapchat was compromised. With every ...

PHP got a whole lot more secure this week with the release of the 7.2 branch, a version that improves and modernizes the programming language's support for cryptography and password hashing algorithms ...
