U-Tranz is a free application developed on the characteristics of UDP allows the transmission of unlimited file size. Most of the applications based on UDP restrict file sharing upto 64kb which makes transmission less efficient on large files. Along with the tremendous increase in file size, certain features like implementation of Government Standard Security Algorithms (AES-256*/RSA-2048 and SHA-512) have been added to this application for secure sharing of huge files across different workstations.This tool programmed in JAVA and requires Java Runtime Environment to use this tool.
