Example

Ruby
  1. require ‘whirlpool’
  2.        
  3. #### Convenience methods:
  4.  
  5. # Returns the Whirlpool hash for "hello world", as raw data.
  6. hash = Whirlpool.calc("hello world")
  7.  
  8. # Same, but returns the hash as a hexadecimal string.
  9. hash = Whirlpool.calc_hex("hello world")
  10.  
  11. #### There’s also an object-oriented way, allowing you calculate the hash
  12. #### by incrementally adding data. The example below has the same
  13. #### effect as Whirlpool.calc("hello world"):
  14. wp = Whirlpool.new
  15. wp.add("hello ")
  16. wp.add("world")
  17. hash = wp.finalize      # Returns the hash as raw data.
  18.  
  19. # After having called finalize, you must either reset the
  20. # Whirlpool object, or create a new one, if you want to calculate
  21. # a new hash:
  22. wp.reset
  23. wp.add("hello ")
  24. wp.add("world")
  25. hash = wp.finalize
