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.

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 ...

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 ...

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 ...

Security researchers have achieved the first real-world collision attack against the SHA-1 hash function, producing two different PDF files with the same SHA-1 signature. This shows that the algorithm ...

For the math-phobic out there, don't let the word scare you. An "algorithm" is nothing more than a set of instructions, just like a recipe or how-to book. And the Internet relies on many, many ...

Researchers have produced a collision in iOS’s built-in hash function, raising new concerns about Apple’s CSAM-scanning system — but Apple says the finding does not threaten the integrity of the ...
