SCREAM CIPHER (“ǠĂȦẶAẦ ĂǍÄẴẶȦ”) Author: Seth Larson | Date: 2025-09-13 --- Introduction The article introduces the playful concept of a "scream cipher," a humorous twist on traditional stream ciphers. It leverages the large variety of Unicode characters, specifically many "Latin capital letter A" variants beyond the 26 letters of the English alphabet, to encode text with visually striking accented letters. --- The SCREAM Cipher The cipher maps each English letter (A-Z, case insensitive) to a unique Unicode letter variant with accents and diacritics. Encoding ("screaming") transforms normal text into a string of these exotic Unicode characters. Decoding ("unscreaming") reverses the transformation to recover the original plain text.
