influido en la historia
Están por todas partes: en tu tarjeta de crédito, en tu móvil o en tu módem. Se trata de los códigos secretos, un procedimiento tan antiguo como Homero, quien ya los utilizaba. César, los adoraba. También los usaban los templarios o Enrique IV, quien abusó de los códigos en su correspondencia amorosa.
Han causado guerras, han hecho ganar batallas y puesto en una situación complicada a Estados Unidos (recordad el caso Snowden). Han influido en el desarrollo del comercio, estaban presentes en las intrigas palaciegas...
En estas líneas encontrarás: cifrado zigzag, código púrpura, discos de Alberti, la palabra probable de Bazeries, el cilindro de Gripenstierna, Enigma, máscaras perforables, Vernam, el sistema RSA, y algunos más.
Os presentamos la obra imprescindible para descifrar misterios. Es eminentemente práctico, en cada capítulo encontrarás una explicación y una propuesta para resolver o traducir diferentes textos a partir de la clave explicada.
