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.

Cryptographic hash functions are crucial in ensuring the security and integrity of information across diverse industries. They protect sensitive financial transactions in banking, verify data ...

A rainbow table is a large, precomputed table designed to cache the output of cryptographic hash functions to decrypt hashed passwords into plaintext. Rainbow tables were invented by IT expert ...

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 ...

The original author of the MD5 password hash algorithmhas publicly declared his software end-of-life and is "no longer considered safe" to use on commercial websites. This comes only a day after a ...

NIST issued a Call for a New Cryptographic Hash Algorithm (SHA-3) Family in a Federal Register Notice on Nov. 2, 2007. The announcement specifies the submission requirements, the minimum acceptability ...

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 ...
