The investigation will look at one of the most common password cracking methods by using the UNIX developed software John The Ripper and RainbowCrack. This review will allow greater insight into the security features and possible vulnerabilities within this mechanism following an investigation. Following this, an insight into password cracking methods will be reviews, identifying the use of dictionary attacks, brute force attacks and rainbow tables. This essay will review academic and published literature on password hash functions, specifically identifying MD4, MD5, SHA algorithms, as well as the use of Salt strings within the Linux OS. ![]() However, within the encryption of these passwords, there are still vulnerabilities faced. Within most systems, passwords are stored by encryption in order to allow security for each user. ![]() ![]() Introduction Passwords are one of the most widely used authentications systems to prevent unauthorised users gaining access to a system, whether that be offline or online. ![]()
