Cryptographic hash functions have many applications in information security and are commonly used to verify data authenticity.

But computer scientists have figured out how the student can satisfy the audience members’ concerns using hash functions. A hash function is like a mathematical blender — it swirls a bunch of data ...

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 ...

Google and Amsterdam-based researchers show a widely-used encryption algorithm is broken. Here's what that means and why it matters to the average consumer.

Records are bundled together into blocks and added to the chain one after another. The basic parts: Hash codes keep records safe. A hash code is created by a math function that takes digital ...

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.
