What is a hash algorithm?

Computer programmers have been using hash functions for decades. These functions are usually used in security, data access, or data verification. Hashing algorithm is a mathematical function that converts characters string with variable length to a fixed numeric value. Today there are more types of algorithms. Each type is designed for a specific purpose.

and the hash function is a mathematical function that creates a hash value from a set of characters chains. When creating a hash function, it is important to protect against has has has has hash. Unfortunately, the hash algorithm can create the same hash value with another set of character data. This will cause a collision because two sets of data will have the same hash key. Data encryption

is one of the primary guarantees against intruders and harmful activities. Science of data encryption is known as cryptography. Hashing algorithm is a computer function that converts the standard data to encrypted format. Today there are many types of safety types of hashalgorithms. Each function has a different level of complexity for security purposes.

Hashing technique was first created as a method of improving performance in computer systems. The hash value is a numerical representation of data characters. Numerical data have faster processing characteristics in search of data files. Many commercial databases use hash files as a data indexing method in database management (DBMS).

The

Hashing process was also used as a method of protecting sensitive computer data. Hashed data requires the encryption program to convert the hash data back into a format that can be understood by human interpretation. It is almost impossible to decipher an encrypted data file without the original hash algorithm.

Progress Hashing Algorithm requires special keys that are used for encryption and decrypting data. These keys are a secret component for the production of the encryption complex. CipherThe key can spread 64 bits per 256 bits. As the size of the bits increases, the complexity of the hash algorithm is more difficult to break.

Cryptography and hash algorithms are controlled by the National Institute for Standards and Technologies (NIST). This group manages standards for encryption functions for use in the United States government. Currently, the standard encryption standard (AES), which requires a 256 -bit key, is defined.
