A Scrambler (Cipher) is a method used to encode information by rearranging its characters or symbols. This technique transforms the original message into a seemingly random sequence, making it difficult for unauthorized individuals to understand. Scramblers are often used in telecommunications and data security to protect sensitive information from eavesdroppers. Unlike traditional ciphers, which may substitute letters or numbers, scramblers focus on shuffling the order of the characters. This can be achieved through various algorithms, ensuring that the original message can be reconstructed only by those who possess the correct key or method. Scramblers are a fundamental part of modern cryptography, alongside other techniques like substitution ciphers and transposition ciphers.
