Cipher Dict

Cipher Dict

Simple+
DE English FR PL UK ZH-HANS

In this mission, you need to convert a plain text to a nested cipher dictionary according to the following steps. This conversion is opposite to one in Cipher Dict (decryption) mission.

  1. Encode the given plain text to utf-8.

  2. Convert this value as a hexadecimal number, then convert the result it to a decimal number. (Every digit of this number will be a key in some level of nested dictionary.)

  3. Split decimal number into blocks with strict ascending/descending order (no same digit repetition allowed in the same block, instead it starts a new one). Blocks order should be strictly alternated and the first block must be ascending. A block may contain one digit of it's necessary to keep alternated order.

  4. Now, you need to fill nested dictionary. Each separate block of digit includes keys of the same dictionary, the values as always empty dictionaries. Taking blocks from left to right, you create a nested dictionary in such a way that digits of every next block become keys in the next (in creation order) empty dictionary. Keep in mind the order of blocks and order of digits inside each block.

The description may be confusing, so let's look at the example.

example

Input: A plain text as a string.

Output: A cipher data as a nested dictionary.

Examples:

get_cipher("hello") == {4: {4: {8: {3: {7: {0: {4: {}, 7: {}}, 2: {2: {}}}, 8: {3: {}}}}}}}
get_cipher("This is a plain text.") == {1: {3: {2: {1: {4: {7: {4: {1: {0: {}, 2: {}, 7: {}}, 4: {9: {}}, 8: {3: {}}},
                                      6: {8: {1: {}, 4: {}, 9: {}}}}}, 9: {5: {5: {6: {1: {}, 4: {}}, 8: {}}}}}}}},
                                      2: {6: {2: {8: {4: {9: {5: {2: {}, 8: {}}}}}}}}, 3: {2: {4: {1: {4: {8: {3: {0: {},
                                      2: {}}}}}, 3: {5: {3: {5: {4: {}, 7: {}}}}}}}}}

How it’s used: (It may not be valuable as a cipher, but it will be useful for studying character code conversion and dictionary structure.)

Precondition: The text contain only ASCII symbols.

CheckiO Extensions

CheckiO Extensions allow you to use local files to solve missions. More info in a blog post.

In order to install CheckiO client you'll need installed Python (version at least 3.8)

Install CheckiO Client first:

pip3 install checkio_client

Configure your tool

checkio --domain=py config --key=

Sync solutions into your local folder

checkio sync

(in beta testing) Launch local server so your browser can use it and sync solution between local file end extension on the fly. (doesn't work for safari)

checkio serv -d

Alternatevly, you can install Chrome extension or FF addon

checkio install-plugin
checkio install-plugin --ff
checkio install-plugin --chromium

Read more here about other functionality that the checkio client provides. Feel free to submit an issue in case of any difficulties.
