## Hash functions in programming languages

The above hashing algorithms are supported by most programming languages. Here, I would like to suggest some general libraries in a number of popular programming languages.

## How many hash algorithms are there?

There are many types of hashing algorithm such as Secure Hash Function (SHA-0, SHA-1, SHA-2, and SHA-3), Message Digest (MD, MD2, MD4, MD5 and MD6), RIPEMD (RIPEND, RIPEMD-128, and RIPEMD-160), or Whirlpool (Whirlpool-0, Whirlpool-T, and Whirlpool).

## Which is the best hash algorithm?

Perhaps the most commonly used one is SHA-256, which is recommended by the National Institute of Standards and Technology (NIST) instead of MD5 or SHA-1. The SHA-256 algorithm returns a 256-bit or 64-digit hexadecimal hash. SHA256 also overcomes the shortcomings of MD5

## Where is hashing algorithm used?

The hashing algorithm is used for many different purposes. In the technique is sometimes used to index data (for example apply in creating index in database). The hashing algorithm is one-dimensional encryption, it will generate a unique hash string from the input of a text, so it is used to compare text integrity. The example used to check whether the software has been modified (inserted with malicious code) compared to the original? Can often be used for digital signatures or digital contracts

## What are the two most common hashing algorithms?

Two of the most common hash algorithms are the MD5 (Message-Digest algorithm 5) and the SHA-1 (Secure Hash Algorithm). MD5 Message Digest checksums are commonly used to validate data integrity when digital files are transferred or stored.

## What is the fastest hash algorithm?

SHA-1 is fastest hashing function with ~587.9 ms per 1M operations for short strings and 881.7 ms per 1M for longer strings. MD5 is 7.6% slower than SHA-1 for short strings and 1.3% for longer strings. SHA-256 is 15.5% slower than SHA-1 for short strings and 23.4% for longer strings
