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 ...

Recent hash table development raises questions about an optimal solution. Hash tables are one of the oldest and simplest data structures for storing elements and supporting deletions and queries.

TL;DR Hash is both a noun and a verb. Hashing is the act of converting passwords into unreadable strings of characters that are designed to be impossible to convert back, known as hashes. Some hashing ...

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 ...

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 ...
