Para el "sincrónico" (contrario al "asíncrono") comúnmente también usan el término "secuencial", porque la computadora / programa sigue todos los pasos en secuencia antes de cambiar a una tarea diferente, incluso si esos pasos implican esperar.

## Hashing de contraseñas

"Hacer hashing" significa convertir algún contenido (una contraseña en este caso) en una secuencia de bytes (solo un string) que parece un galimatías.

Siempre que pases exactamente el mismo contenido (exactamente la misma contraseña) obtienes exactamente el mismo galimatías.
