Bloom filters are an essential class of probabilistic data structures designed for rapid set membership testing while minimising memory usage. By utilising multiple hash functions, these structures ...

Hashing is a one-way cryptographic function while encryption is designed to work both ways. Encryption algorithms take input and a secret key and generate a random looking output called a ciphertext.

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 ...

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 ...

Anyone with an interest in bitcoin will have heard the phrase 'cryptographic hash function' at some time or other. But what exactly does it mean, and how is it connected to cryptocurrency? Hash ...

What is Bitcoin’s hash rate? The amount of processing and computing power being given to the network through mining is referred to as Bitcoin’s hash rate. A fixed-length alphanumeric code representing ...
