Abstract

LibreSSL je implementacija protokola TLS nastala iz OpenSSL-a s ciljem modernizacije programske baze, poboljšanja sigurnosti i primjene najboljih praksi razvojnih procesa. Sastoji se od biblioteke kriptografskih funkcija i pomo´cnih programa. Ovaj rad daje uvid u LibreSSL bibilioteku i kako ju koristiti. Korak po korak je prikazan naˇcin implementacije LibreSSL biblioteke u programskom jeziku C. Pokazani si koraci instalacije biblioteke na korišteni operacijski sustav, korištenja funkcija koje LIbreSSL nudi u kodu te kompajliranje koda sa LibreSSL datotekom. Na primjeru implementacije, kroz alat Wireshark pokazano je ponašanje klijenta i poslužitelja koji komuniciraju putem TLS protokola.

Abstract (english)

LibreSSL is an implementation of the TLS protocol forked from OpenSSL with a goal of modernizing the code, increasing security and using best in practice development processes. It is made of library of cryptographic functions and auxiliary programs. This thesis gives an insight into LibreSSL library and how to use it. Step by step it is shown how to implement the LibreSSL library in programming language C. The steps shown are how to install the library on the used operating system, use of functions that LibreSSL offers in code and compiling the code with LibreSSL library. OnimplementationexampletroughWiresharktoolbehaviourofclientandserverwere shown while they are communicating trough TLS protocol.
