We can encrypt sensitive content, say “my_content” with openssl with different encryption algorithms in the below manner: # encrypt string with algorithm pbkdf2 with randomly generated salt and input passwordĮcho "my_content" | openssl enc -pbkdf2 -a -salt -pass pass:my_password Passwords are the primary method that Red Hat Enterprise Linux 7 uses to. Lets say we have a file with some sensitive content. Enterprise Linux 8 (CentOS 8, RHEL 8, Rocky Linux 8, AlmaLinux 8) Repository: EPEL aarch64 Official: Package filename: 64.rpm: Package name: pwgen: Package version: 2.08: Package release: 3.el8: Package architecture: aarch64: Package type: rpm: Homepage: License: GPL+: Maintainer-Download size. Openssl passwd -crypt -salt my_salt my_password See how to use makepasswd> command to generate true random passwords by using the /dev/random feature of Linux. # generates hashed password with crypt algorithm + salt To generate 8 character long random password, enter: genpasswd 8 Sample outputs: oj7Wqvb Linux Random Password Generator Command. ![]() This tool will help us generate some random yet meaningless passwords. With openssl, we can generated hashed-passwords for supplied password as input: # generates hashed password with crypt algorithm For using pwgen we need to install this tool first. code For the bpwgen /b command, I can find i bsecpwgen /i /b. # generates 12-character password and encrypted md5 password You should install bind-utils if you need to get information from DNS name. Makepasswd -chars=12 -crypt -cryptsalt=20 # generates 12-character password and encrypted password with crypt algorithm + salt We can generated encrypted passwords with utilities like makepasswd: # generates 12-character password and encrypted password with crypt algorithm # generates specified 12-character passwords, say 5 # generates multiple 12-character passwords We can utilities like mkpasswd or pwgen to generate random passwords if needed: # generates multiple 8-character passwords We can use the same to encrypt and decrypt passwords in Linux to protect sensitive data. For example, you can add the following bash shell function to your ~/.OpenSSL is one of the utilities available with all major Linux distributions. ![]() Of course, there are many other ways to generate a strong password. We can also use the gpg tool to generate a strong 14 characters password: Use sha1 hash of given file as a (not so) random generatorĭon't print the generated passwords in columnsĭo not use any vowels so as to avoid accidental nasty words Bash shell hack to generate random passwords on the Linux/Unix command line. The pwgen command generate pronounceable passwords. The makepasswd command generates true random passwords using /dev/urandom. The updated version of generate new password, optionally apply it to a user. For example, I chose to generate a 15 character password from this command. Afterward, you will use the pwgen command to specify the password string length you wish to generate. The installation duration should take less than a minute to complete. Include at least one special symbol in the passwordĭon't include ambiguous characters in the password It can also encrypt plaintext passwords given on the command line. sudo apt install pwgen sudo pacman -S pwgen sudo yum install pwgen. Include at least one number in the password Include at least one capital letter in the passwordĭon't include capital letters in the password ![]() You can also use some of the following flags: Once the installation is complete, use the following command to generate a random string of 14 characters: pwgen 14 1 mo GET YOUR VPS sudo apt-get install pwgen
