Hash tables are heavily used within the kernel to speed access to objects of interest. Using a hash table will be faster than, say, a linear search through a single list, but there is always value in ...

The traditional way of implementing a hash table is to have an array of linked lists. However, user-space RCU instead uses a split-ordered list, which provides a lock-free RCU-protected resizable hash ...

Hash tables are data structures that manage space, originally for a single application’s memory and later applied to large computing clusters. As hashing tables are applied to new domains, old methods ...

The National Institute of Standards and Technology published the final version of its "Secure Hash Algorithm-3" standard in August 2015 and has released it to the public, calling it a "next-generation ...

The National Institute of Standards and Technology (NIST) this week opened a competition to develop a new cryptographic hash algorithm, a tool that converts a file, message or block of data to a short ...

The first time I heard about hash tables was after taking a compilers course during my BSc. The truth is, I was not able to understand and appreciate their usefulness fully back then. Now that I know ...

A rainbow table is a large, precomputed table designed to cache the output of cryptographic hash functions to decrypt hashed passwords into plaintext. Rainbow tables were invented by IT expert ...

Many organizations have been replacing the MD5 hash algorithm with the SHA-1 hash function, but can the MD5 hash algorithm still be used securely? MD5 (Message-Digest algorithm 5) is a cryptographic ...
