English Abstract

-With today’s technology, a user can store his/her whole life on computer hard drive.

With password protection, everything is safe.

A password works as a strong lock thatprotects information and data in any personal computer or large system.

Humans can easily create memorable passwords, but this also creates the problem that the generating process is guessable either online/ offline, or by dictionary attacks, brute force attacks, Rainbow Tables or by Social Engineering techniques.

In this thesis, an effective method to generate random passwords has been created and implemented using Huffman coding algorithms.

In the creation phase, the user enterssix characters from four different groups (capital characters, small characters, digits, and symbols), the program generates different passwords.

The generated passwords are classified into five scores according to Huffman Coding entropy scores.

The passwords which we obtain fromHuffman Coding results will be checked again according to Password Meter checking weight schemas.

Therefore, the good results obtained through the system indicate its ability to create a safe and strong password.
