Transposition ciphers take the regular plaintext and change the order of words, syllables and letters to achieve the ciphertext. Typically, greater security is achievable when the smallest unit transposed is every letter. There are a wide variety of transpositions mainly due to the variations possible within broad categories of transposing styles.
I tried some Anagrams.
I tried a Pyramidal Transposition on the Morse Code.
I tried a Rail Cipher on K1.
I tried a Rail Cipher on K4.
I tried a Rail Cipher on the Morse Code.
I tried a Grille Cipher on the Copperplate.
I tried a Route Transposition Cipher on the Morse Code.
I tried making a Kryptos Cipher Wheel.
I looked at some Monoalphabetic Uniliteral Transposition Tables.
I tried to reverse Keyed-Columnar Transposition on the Morse Code.
I also developed a pencil/paper Columnar Transposition Solution method.
I used the merged K4/Morse code text and tried a keyed-columnar.
I tried a Route Transposition on K1.
I tried a Columnar Transposition on K4.
I toyed with the idea that K4 was a double transposition.
I tried a K4 Permutation Cipher.
I tried a Rotational Transposition Cipher on K4.
I checked to see if K4 was a Scytale.
I tried the Ubchi cipher on K4.
I tried a Permutation Cipher.
I looked into the Rasterschlüssel Cipher.
