A hash function takes a group of characters (called a key) and maps it to a value of a certain length (called a hash value or hash). The hash value is representative of the original string of characters, but is normally smaller than the original. Advertisements Hashing is done for inde...
What is Hash Function? Think of termhashas used in cooking like a hash brown. We take raw ingredients, chop them and mix them all together. Our raw ingredients are data like strings in our example or something like a password or maybe an entire object. All we do is add this data to ...
For websites, security is crucial when it comes to dealing with user data. Most website owners choose to usecryptographyhashing to keep login credentials safe. The hash function takes input data of any size, like yourpasswordor a user file, and converts it into a fixed-length "hash value"...
A data structure is a specialized format for organizing, processing, retrieving and storing data. There are several basic and advanced types of data structures, all designed to arrange data to suit a specific purpose. Data structures make it easy for users to access and work with the data they...
Falling under the ‘Map’ interface in the Java Collections Framework, HashMap offers a dynamic and flexible means of organizing data. The HashMap works on the principle of hashing, which involves converting the key into an index using a hash function. This index determines the bucket where the...

This algorithm is a one-way cryptographic function as the original data can be retrieved via decryption. The implementation of a cryptographic hash function is beneficial to prevent fraudulent transactions, double spends in blockchain, and store passwords. But, what is Bitcoin hash, and what does ...
Hash table Hash-based structures map keys to values using hash functions that associate related data by assigning indices to hash tables. Document-oriented databases Document-oriented databases organize quantities of information about an entity into a single object (the document), which is separate...
The hash function requires both key and the value. The key contains the logic that determines what index the value will live at within the underlying data structure (array or object). When we use objects as storage, the index is often just some string or integer version of the key. When...
Hashing in blockchain is a cryptographic function that creates an encrypted output of a specified length from an input of characters and numbers. Read on.
