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 ...

RSA and hashing are two cryptographic functions that are widely used together. RSA provides the encryption using a public and private key, and hashing creates a binary fingerprint. For example, in a ...

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 ...

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 ...

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 ...

In this episode of “Bitcoin, Explained,” hosts Aaron van Wirdum and Sjors Provoost go back to Bitcoin basics. They explain one of the most fundamental building blocks in all of Bitcoin: hash functions ...

Now that SHA-1 has been broken it’s time for enterprises that have ignored its potential weakness for years to finally act, and it’s not that hard. The most common use of the hash function is 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 ...

For more than six years, the SHA1 cryptographic hash function underpinning Internet security has been at death’s door. Now it’s officially dead, thanks to the submission of the first known instance of ...
