Am gasit ceva funny in python si totodata foarte folositor.

Introduceti comanda de mai jos in python si veti intelege despre ce e vorba ;-)

^ Presupun ca textul respectiv e in rot13, nu ?

L.E. am trecut peste lenea inerenta acestei ore si am verificat. Am avut dreptate, este rot13.

Mie mi se pare o encriptare destul de slaba, dar pentru cei care nu stiu poate fi ceva serios.

Ave Caesar ;))

P.S. Se vede ca e ROT-13 din for

Nu m-am uitat la cod, dar mi se parea cunoscut stilul. Am mai butonat nitel pe rot13 acum cativa ani si da, este o encriptare foarte slaba (cu atat mai mult ca e si simetrica - desi rotN n-ar fi cu mult mai puternica).

Ave Caesar, indeed.
