Substitution and Index¶
Substitution¶
Anything can be replaced by numbers.
- Look for group of 6/10/14/15 digits. If you have a large amount of items, you are looking for a text message, not numbers.
- Alphabet
- Atom numbers of elements
- Change keyboard layouts (including Dvorak)
- Use a different font (Symbols, WingDings, …)
- Substitute arbitrarly and go through a cryptogram
