The relation of the hash function to the key and the hashes



  • Hash algorithms are used to associate certain keys with files.
    • This is usually done in situations where many keys are associated to only few hashes, or vice versa.
  • Hash algorithms create hashes from the keys depending of their composition. The hashes are then used to determine the record or file they are linked to.
