A simple substitution cipher operates by replacing every letter of a plaintext alphabet with a corresponding letter or symbol from a ciphertext alphabet. While this creates an enormous number of possible keys (approximately asc substitution crack
| Type | Description | Example | |------|-------------|---------| | | Each ASCII code is shifted by N (mod 128) | A (65) → D (68) | | XOR with constant | Bytewise XOR with a single key byte | A (0x41) ^ 0x20 = a (0x61) | | Arbitrary mapping | Any character mapped to any other | A → % , B → 9 | | Subset rotation | Only letters rotated; symbols unchanged | A-Z shifted, 0-9 shifted separately | | Atbash (ASCII) | Mirror within range: code i → code (127 - i) | A (65) → > (62) | Changes can be published directly to mobile apps
