title: Hash Functions which are used and more popular
body: <p>I know the list of all hash functions is too long. I just want to know the most popular ones which are used in day to day IT practical tasks. I know MD5, SHA1, SHA2 (256 and 512) are really popular. Is there any other hash function I can add to these 5 algorithms?</p>
  
  <p>I want to develop a hash Tool and I just want to include those algorithms that developers really need.</p>
