Studying password encryption techniques is important to the information security discipline because it demonstrates the vulnerability of weak passwords and the need for better security measures to protect sensitive information. Although two methods have been developed to crack passwords, both perform different tasks. While brute force algorithms create all the characters together into a common long phrase, the dictionary has a hard time checking the word list first. This workuses parallel versions of Python, C++ and Hashcat to compare the results of these methods.The results show that NVIDIA GeForce GTX 1050 Ti using CUDA can crack passwords faster than Intel(R).HD Graphics 630 GPU, the password speed is 11.5x and 10.4x respectivelyand . Special characters increase password cracking time and make the cracking process more difficult. Our results showed that theequation greatly increases password processing speed. The brute force algorithm reaches 1.9x speedup on six cores, while the stop dictionary reaches 4.4x speedup on eight cores with static scheduling. Research on password encryption techniques demonstrates the need for better security measures to protect sensitive data and the vulnerability of weak passwords.
