Shift each letter 5 places to the right in the alphabet. If the letter is already at the end of the alphabet, wrap around to the beginning.

| Idea | How it works | |------|----------------| | | Swap every two characters. “HELLO” → “EHLLO” | | Add a key number to each char code | ord(char) + 5, but wrap around 255 | | Substitution cipher | Map A→M, B→N, etc. (shift with a pattern) | | Bitwise XOR | XOR each character with a fixed key | | Custom dictionary | Replace common words with symbols | Shift each letter 5 places to the right in the alphabet
for (var len = 2; len >= 1; len--) var slice = encodedMessage.substr(i, len); if (decodingMap[slice] !== undefined) decoded += decodingMap[slice]; i += len; found = true; break; “HELLO” → “EHLLO” | | Add a key
