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.

Security pros often ask about the weaknesses of the Message-Digest version 5 algorithm (MD5) and whether it should still be used. MD5 is a cryptographic one-way hash function that produces a value ...

If you've ever watched TV and movies about cybersecurity, you probably envision someone sitting in a dark room trying to guess someone else's password based on a few facts like their kids' names or ...

In March, readers followed along as Nate Anderson, Ars Technica deputy editor and a self-admitted newbie to password cracking, downloaded a list of more than 16,000 cryptographically hashed passcodes.

Since then, computer forensic analysts have come to use the term hashkeeper when they discuss ways of using the hash values of files to assist in forensic analysis. I will not attempt to explain or ...

SHA1, one of the Internet’s most crucial cryptographic algorithms, is so weak to a newly refined attack that it may be broken by real-world hackers in the next three months, an international team of ...
