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 ...

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 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 ...

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 ...

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 ...

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 ...

With the rapid development of digital communications, sensitive digital storage security, especially that of images, remains a significant challenge. Most of the existing hash algorithms cannot meet ...
