Symboolvervanging

Leren

Letters worden vervangen door symbolen volgens een gegeven sleutel.

Symbol substitution codes replace letters with symbols (@, #, $, %, etc.) according to a provided key. Unlike alphabetic shifts, there's no predictable pattern—you must use the key exactly as given. The key may only cover some letters, with others following a different rule.

A=@, B=#, C=$, etc. (as specified in key)

• If A=@, B=#, C=$ then ABC = @#$
• If X=!, Y=?, Z=* then XYZ = !?*
• Decode #@$ using A=@, B=#, C=$ → BAC

Zo herkent u het

• Message contains symbols not normally in words
• A key is provided mapping letters to symbols
• No predictable pattern—must use the key

Veelgemaakte fouten

• Trying to find a pattern instead of using the key
• Confusing similar-looking symbols
• Misreading which symbol maps to which letter
