Cycle cipher

WebIn cryptography, format-preserving encryption ( FPE ), refers to encrypting in such a way that the output (the ciphertext) is in the same format as the input (the plaintext ). The meaning of "format" varies. Typically only finite sets of characters are used; numeric, alphabetic or alphanumeric. For example: WebFeb 23, 2024 · To overwrite deleted data on a volume by using Cipher.exe, use the /w switch with the cipher command: Quit all programs. Select Start > Run, type cmd, and then press ENTER. Type cipher /w: folder, and then press ENTER, where folder is any folder in the volume that you want to clean.

But, with standard Encryption with a secret key using AES/GCM, the cipher text after encrypting is much longer in length than the original text. Since, each database column has a specific length, I do not want the encrypted text to be longer than the original text.

WebA "cycle" of letters runs from the top row, down through each subsequent row, and then up again, but stopping before reaching the top row again. (The next letter on the top row will actually begin the next cycle.)
