SMS Kod

Multitap zamenjuje slovo ponovljenim brojevima definisanim odgovarajućim kodom tastera na mobilnoj telefonskoj tastaturi (Ovaj režim se koristi prilikom pisanja SMS poruka). Na primer: 2=A, 22=B, 222=C, 3=D... Možete identifikovati ovaj kod jer ćete videti** više puta ponovljene brojeve**.

Ovaj kod možete dekodirati na: https://www.dcode.fr/multitap-abc-cipher

Bacon Kod

Zamenite svako slovo sa 4 A ili B (ili 1 i 0)
