Abstract

Kriptografske funkcije za izračun sažetaka matematički su algoritmi korišteni za pohranu zaporki. Oni vrše preslikavanje podataka varijabilne veličine u podatke fiksne veličine, a pri tome imaju svojstvo jednosmjernosti, odnosno jedini način otkrivanja zaporke je služenje metodama iscrpne pretrage ili metodama koje potječu iz nje. Jedan od najčešće korištenih algoritama za zaštitu zaporki je bcrypt, spori, sekvencijski algoritam razvijen da bude prilagodljiv na tehnološke napretke. Testiran je na sustavu ugradbenih računala uz pomoć softverskog alata John the Ripper, prilagođenog za izvođenje na programabilnoj logici.

Abstract (english)

Cryptographic hash functions are mathematical algorithms used in password protection. These algorithms map data of arbitrary size into data of fixed size, while also exhibiting the property of being a one-way function, that is, the only way of computing a hashed password is by performing brute-force search or other inefficient methods. One of the most commonly used password protection algorithms is bcrypt, a slow, sequential password hashing algorithm designed to be adaptable to technological advances. It was tested on a distributed system of embedded computers using password cracking software called John the Ripper, specifically adapted for use in programmable logic.
