Dish and Recipe objects

The Dish object is what you start with. Recipes can only be applied to dishes. You create a dish like so: x = Dish("Hello, world!")

A Recipe object will be seen less often, but it can be useful in some cases. Let's say you've made a dish like so, x = Dish("hello world").apply(toDecimal).apply(toMorse), and want to create another dish with the same recipe. The recipe of any dish can be accessed through the .recipe attribute, eg: x.recipe which will return <Recipe: toDecimal -> toMorse>. To make another dish with the recipe from x, you would do: y = Bake("goodbye world", x.recipe).

recipes

Some recipes have no arguments, they are applied like so: x.apply(toBase64). Some recipes require argument(s) and/or keyword argument(s), they can be applied in two ways, either like x.apply(XOR("0110")), or like this x.apply(XOR, "0110"). Both do the same thing.

Similarly, keyword arguments can be applied in two ways. x.apply(toMorse(dot="*")) or x.apply(toMorse, dot="*").

Not all recipes begin with to or from. Some examples of recipies that don't are:

• XOR - this is because to reverse the process, you just apply XOR again with the same key
• split - this is a string manipulation method, it can be 'reversed' with join
• join - this is a list manipulation method, it can be 'reversed' with split

Not all recipes that begin with to have a counterpart. For example, all of the hashing recipes (such as toSHA256). This is because hashes are irreversable by nature.

Examples

Good hashing recipe

from cryptobaker import *

hashr = lambda x: ("salt" + Dish(x).apply(toSHA256)).apply(toMD5)
print(hashr("password")) # '9f3b7f774efa78c8dd6df5e0ff1cb67d'

Encoder and Decoder

from cryptobaker import *

encr = Recipe(toDecimal, toBinary, join(" "), toBase64)
decr = Recipe(fromBase64, split(" "), fromBinary, fromDecimal, join)

enc = encr.cook("Hello, world!")
dec = decr.cook(enc)

dec == "Hello, world!"
