Google is encouraging businesses and security practitioners to utilize cryptographic hashes like SHA-256, a Secure Hash Algorithm which serves as the basis of the Bitcoin network’s proof of work (PoW) ...

Compare SHA-256 vs Keccak-256 cryptographic hash functions, security, performance, and blockchain applications.

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 ...

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 ...

A target hash in cryptocurrency mining defines the difficulty level of finding a new block in a proof-of-work (PoW) system.

Could an IBM mainframe from the 1960s mine Bitcoin? The idea seemed crazy, so I decided to find out. I implemented the Bitcoin hash algorithm in assembly code for the IBM 1401 and tested it on a ...

I am trying to find duplicate audio files in a folder structure that contains a little over 20,000 files. Some dupes will have identical names, others will not. I know that roughly 80%-90% of the ...

The cryptography world has been buzzing with the news that researchers at Google and CWI Amsterdam have succeeded in successfully generating a 'hash collision' for two different documents using the ...
