Frequently asked questions
¿Qué es un hash?
Es una huella digital de datos: una cadena de longitud fija generada a partir del contenido. Cualquier cambio en el texto produce un hash completamente distinto.
¿El hash se puede revertir?
No a nivel práctico. Los hashes criptográficos son funciones unidireccionales: no puedes recuperar el texto original desde el hash.
What is a hash?
It is a data fingerprint: a fixed-length string generated from the content. Any change in the text produces a completely different hash.
Can a hash be reversed?
Not in practice. Cryptographic hashes are one-way functions: you cannot recover the original text from the hash.
