Abstract	Glavni problem rada je bio osmisliti mehanizam za anonimnu razmjenu datoteka te modelirati i programski implementirati što bi rezultiralo aplikacijom na klijentskoj i poslužiteljskoj strani u Linux okruženju. Anonimizacija je postignuta korištenjem Tor programa, a siguran i pouzdan prijenos podataka omogućen je SSH protokolom. Prijenos datoteka omogućen je SFTP protokolom. Aplikacija na poslužiteljskoj strani obavještava klijente kada je dostupna, preuzima datoteke s ključevima za dekriptiranje kriptiranih datoteka koje klijenti postavljaju te ih razašilje klijentima kriptiranom elektroničkom poštom i briše ključeve kako bi kriptirane datoteke ostale kriptirane i nakon eventualne kompromitacije poslužitelja. Klijentska strana aplikacije omogućava korisnicima postavljanje datoteka koje se prije postavljanja kriptiraju. Također im omogućava preuzimanje datoteka koje su kriptirane na poslužitelju i dekriptiraju se na klijentskoj strani odabirom ispravnog ključa koji je klijent dobio elektroničkom poštom poslanom od poslužitelja. Instalacija poslužiteljska strane aplikacije je omogućena za SoC uređaje.
Abstract (english)	The main problem of this thesis was to design a mechanism for anonymous file transfer and programmatically implement this mechanism. Solution of the problem resulted in a client-side and server-side application in Linux environment. Anonymisation was achieved by using Tor software, and secure and reliable data transfer was achieved by using SSH protocol. File transfer was enabled by using SFTP protocol. The server-side application informs clients when it is available, handles files with keys for decryption of files which clients upload, encrypts files with keys and sends them to clients using encrypted e-mails and then deletes files with keys so that encrypted files stay encrypted in case of server compromisation. Client-side application enables its users to upload files which are being encrypted before upload. It also enables its users to download files which are encrypted on the server, and are decrypted on the client-side by choosing the corresponding key for decrypting which user had got by e-mail sent by the server. Installation of the server-side application is enabled for SoC devices
