Tool to shuffle letters. Mixing letters of a message is enough to make it incomprehensible. It is possible to perform blocks permutations to make group of shuffled letters.

Answers to Questions (FAQ)
What is a letter shuffle? (Definition)
Letter shuffling is a method that consists, as its name suggests, of mixing the letters of a message.
This technique can be used during an encryption, which will then be called by transposition, and in this case, the mixture must follow certain rules so that it is reversible.
How to encrypt using a letter shuffler/mixer?
Several methods are possible:
Mix by writing backwards
An easy reversible mixing is to write backward, the message become less readable.
Example: ABCDEF becomes FEDCBA (reversal of order)
Start-end cycle shuffle
The first letter goes at the beginning, the next at the end, then at the beginning and so on
Example: ABCDEF turns successively into A, AB, CAB, CABD, ECABD and ECABDF
Mix by random write
If all the letters are randomly shuffled once, it will be very difficult (if not impossible) to recover the original message without knowing the permutation used.
Split by words
In order not to make too complex mixtures, the message can be broken down into words. It will then generate an anagram of the word (which exists or not).
Split by blocks
For an easier shuffling, the message may be broken down by a fixed block size. Generally, it is best to use short blocks.
Example: If the block size is 2, take the letters in pairs, and reverse their position DCODE becomes CDDOE.
dCode offers a tool for performing transposition ciphers.
How to decrypt a letter shuffled cipher?
Decryption requires to recover the original order of mixed letters.
If it is a word split, find the existing anagrams, and among these, the right original word.
If it is a block split, find the original permutation again several solutions possible, if the permutation is random, find the most logical/plausible one.
If it is a sentence, it is extremely difficult if not impossible in a reasonable amount of time.
What is the typoglycemic shuffling?
dCode has a tool for mixing the letters of a message while keeping it (theoretically) readable by a human: see the typoglycemia tool.
Example: Aoccdrnig to a rscheearch at Cmabrigde Uinervtisy, etc.
