### A1Z26

Letras a su valor numérico
```
8 15 12 1 3 1 18 1 3 15 12 1
```
### Cifrado Afín Codificar

Convertir letra a número `(ax+b)%26` (_a_ y _b_ son las claves y _x_ es la letra) y luego convertir el resultado de vuelta a letra
```
krodfdudfrod
```
### Código SMS

**Multitap** [reemplaza una letra](https://www.dcode.fr/word-letter-change) por dígitos repetidos definidos por el código de tecla correspondiente en un teclado de [teléfono móvil](https://www.dcode.fr/phone-keypad-cipher) (Este modo se utiliza al escribir SMS).\
Por ejemplo: 2=A, 22=B, 222=C, 3=D...\
Puedes identificar este código porque verás\*\* varios números repetidos\*\*.

Puedes decodificar este código en: [https://www.dcode.fr/multitap-abc-cipher](https://www.dcode.fr/multitap-abc-cipher)

### Código Bacon

Sustituye cada letra por 4 As o Bs (o 1s y 0s)
```
00111 01101 01010 00000 00010 00000 10000 00000 00010 01101 01010 00000
