### YEncoder
|
|
|
|
YEncoder es un algoritmo de codificación utilizado para codificar datos binarios en ASCII. Es similar a UUencode y Base64, pero utiliza un conjunto de caracteres diferente para la codificación. YEncoder se utiliza a menudo en CTFs para ocultar información en desafíos de esteganografía.

|
|
|
### A1Z26
|
|
|
|
Letras a su valor numérico
|
|
```
|
|
8 15 12 1 3 1 18 1 3 15 12 1
|
|
```
|
|
### Cifrado Afín Codificación
|
|
|
|
Convertir letra a número `(ax+b)%26` (_a_ y _b_ son las claves y _x_ es la letra) y luego convertir el resultado a letra de nuevo.
|
|
```
|
|
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

|
|
```
