The output will be the generated password hash, which you can use for password storage or authentication purposes. To generate an SHA-512 password hash with the password “tecmint”, you can use the following command: $ mkpasswd -m sha-512 tecmint Running the above command will generate a random salt value and use it to create the password hash for the password “ tecmint.” The output will include the generated password hash. Hence every time you run the below command it will generate different outputs because it is accepting a random value for salt every time. The salt value is taken randomly and automatically. Now run the makepasswd command, which will encrypt the password with salt. The mkpasswd command is a part of the whois package, and it is not installed on most modern Linux distributions, you need to install it using your distribution’s package manager. To encrypt a password using crypt (a Python standard library) along with the salt method.įor those who may not be aware of salt, which is random data that serves as an additional input to a one-way function in order to protect passwords against dictionary attacks. Makepasswd – Generate Random Passwords mkpasswd – Encrypt a Password in Linux To generate 7 random passwords of 20 characters. To generate a random password of character length 50. To generate a random password of character length 10 (default value is 10). If not, you may install it using your distribution’s package manager as shown. The makepasswd command is another password generator that is used to generate unique random passwords based on a given length.īefore you can use the makepasswd command, make sure you have installed it. Pwgen – Generate Random Passwords Makepasswd – Generate Unique Passwords on Linux To generate several random unique passwords of character length 50 in one go, use: $ pwgen 50 Once ‘ pwgen‘ is installed, you can use it to generate a single password as shown. If you have not installed pwgen, you can install it using your respective package managers as shown. To generate a random unique password of length equal to 10 characters use the ‘ pwgen‘ command. PWgen – Generate a Random Password on Linux What about some sort of machine-based password generation automatically using pwgen or makepasswd – a command-line password generator used to generate random passwords based on length, complexity, and character. We all know the basic to choose a password that is easy to remember and hard to guess. We set passwords to computers, email, cloud, phones, documents, and whatnot. Security is one of the major concerns of the digital age. In this article, we will share some interesting command-line tools to generate random passwords and also how to encrypt and decrypt passwords with or without the slat (a security measure used in password hashing) method.
