Given only the hash, an attacker should have no clue about the original message, not even the size of the message (which, obviously, is not the case of the first example).īesides that, cryptographic hash functions have the following characteristics: This means that it is practically impossible to recreate the input of the function (normally called message), by looking only at the output of the function (called message digest).ĭifferently from regular hash functions, which also have some difficulty to be reversed, cryptographic hash functions are very hard to invert even if the attacker knows the theory and the algorithm used. Hash tables can be very efficient when used with a good hash function.Ī cryptographic hash function is non-invertible, or, in other words, a one-way-function. These tables use hash functions to compute an index into an array of slots. Some modern programming languages, like Ruby, have data structures called hash tables, which are used to implement dictionaries, which maps keys to values.
Note that, for this function, it is not hard to find examples of different keys that will be mapped into the same integer.
This hash function will simply count how many letters are in the name to find the correspondent integer. That is a hash function that maps names of arbitrary length to an integer. Take the following picture as an example: Introduction - What are Hashes?Ī hash function is defined as a function that maps data of arbitrary size to data of fixed size.
