Disrupted Transposition Cipher
The Disrupted Transposition Cipher is a variation of the classical columnar transposition cipher that introduces irregular row filling to obscure structural patterns. Unlike standard transposition, where plaintext is written into a complete rectangular grid, the Disrupted Transposition Cipher intentionally “disrupts” the layout by filling rows unevenly based on a keyword pattern. This irregularity makes it more difficult to reconstruct the original grid during cryptanalysis.
AMSCO Cipher
The AMSCO Cipher is a transposition cipher that rearranges the letters of a message using a keyword and an alternating cell pattern. Unlike simple columnar transposition, AMSCO alternates between placing one and two characters in each cell, following a continuous pattern (1-2 or 2-1) across the entire message.
Kangaroo Cipher
The Kangaroo Cipher is a simple substitution cipher that uses a keyword to generate a variable shift pattern across the plaintext. It is similar in concept to the Caesar Cipher but instead of a single uniform shift, each letter is shifted according to the corresponding letter in the keyword, which repeats across the message.
Transposition Cipher
The Transposition Cipher is a classical cipher technique that rearranges the letters of the plaintext according to a defined system, without changing the letters themselves. Unlike substitution ciphers, where letters are replaced with other letters or symbols, transposition ciphers preserve the original letters but change their positions to create the ciphertext.
Rail Fence Cipher
The Rail Fence Cipher is a classical transposition cipher that rearranges the letters of a plaintext message into a zigzag pattern across multiple "rails" (rows) and then reads them sequentially row by row to form the ciphertext. It is a simple but effective method for obscuring the order of letters, making it harder for casual observers to read the message without knowing the number of rails used.
