Frequently Asked Questions

What is a hash algorithm?

Hash algorithms have been around for decades and are used for applications such as table lookups. For example, you can use a person’s name and address as a hash key used by a hash algorithm.

What is the SHA-1 hashing algorithm?

SHA-1 is one of the main algorithms that began to replace MD5, after vulnerabilities were found. SHA-1 gained widespread use and acceptance. SHA-1 was actually designated as a FIPS 140 compliant hashing algorithm.

What is a one-way hash algorithm?

A one-way hash is an algorithm that transforms a string into another string in such a way that the original string cannot be calculated by operations on the hash value (hence the term “one-way” hash). Popular one-way hash algorithms are MD5 and Standard Hash Algorithm.

What is Zobrist hashing algorithm?

This algorithm has proven to be very fast and of high quality for hashing purposes (especially hashing of integer-number keys). Zobrist hashing was originally introduced as a means of compactly representing chess positions in computer game-playing programs.
