A mathematical formula that accepts a quantity of data and derives a number known as a "hash" or "hash value." See hash and cryptographic hash function. THIS DEFINITION IS FOR PERSONAL USE ONLY. All ...

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 ...

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 ...

How mining works is fascinating. When I explain it to people, I enjoy seeing their face the moment their mind is blown. I’ll explain it here, but just know, I’m imagining all your faces as your minds ...

The National Institute of Standards and Technology retired one of the first widely used cryptographic algorithms, citing vulnerabilities that make further use inadvisable, Thursday. NIST recommended ...

Many of today’s computer passwords are stored and transmitted in a cryptographic hashed form. A strong password hash algorithm ensures that if the password hash is obtained by unauthorized parties ...

Members can download this article in PDF format. In the last two articles, we covered the basic concepts and two basic types of cryptography. In this article, we will look at specific implementation ...

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 ...

Cryptographic hash functions secure data by providing a unique fixed-length output for each input. These functions are essential in blockchain for data integrity and secure transactions. Understanding ...
