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?
I want to develop a hash Tool and I just want to include those algorithms that developers really need.
Most widely used (and defined in standards for SSL/TLS, OpenPGP, SSH) are:
There are also other hash algorithms (you can get the full list on wikipedia), but most likely you'll never meet them in real life.
