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 ...

Understanding Bitcoin is a one-way hash function should make sense because a hash function cannot be reversed. Once you understand that, it is hard to go back to thinking otherwise. The secure hash ...

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 ...

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 ...

An algorithm that transforms a given amount of data (the "message") into a fixed number of digits, known as the "hash," "digest" or "digital fingerprint." Hash functions are a fundamental component in ...

The SHA1 (Secure Hash Algorithm 1) cryptographic hash function is now officially dead and useless, after Google announced today the first ever successful collision attack. SHA1 is a cryptographic hash ...
