A cryptographic hash function (chf) is a hash algorithm (a map of an arbitrary binary string to a binary string with a fixed size of bits) that has special properties desirable for a cryptographic application: [1] finding an input string that matches a given hash value (a pre image) is infeasible, assuming all input strings are equally likely. Step 2: next, you feed your data into the function. this could be anything—a password, a document, or even an entire software program. your data is the ingredient in your hash recipe. step 3: the function then chops up your data, mixes it around, and cooks it up into a hash. 12.1: defining security. superficially, it seems like we have already given the formal definition of security: a hash function h is collision resistant if no polynomial time algorithm can output a collision under h. unfortunately, this definition is impossible to achieve! fix your favorite hash function h.
