Personally, the only time I’ve been generating a SHA512 password hashes was when I was working with ansible.builtin.user module, simply because I needed to commit a password hash for a new Linux user. Although I wouldn’t consider it as an optimal solution (not even close), let’s see how to create one.
Prerequisites
- Shell environment
- sudo privileges
Solutions
Solution 1. Use mkpasswd
Step 1. Install mkpasswd.
sudo apt install whois
Step 2. Generate SHA512 password hash with a salt.
mkpasswd --method sha-512 <SOME_PASSWORD_HERE>
Note(s):
- If you don’t add parameter
-S, --salt=<SOME_STRING_HERE>, it will use a random salt value. - If you want to keep it OS agnostic (since mkpasswd it’s not available to macOS and Windows, although you could install it via gem or npm), use Docker. For instance:
docker run -it --rm alpine mkpasswd --method=sha-512 <SOME_PASSWORD_HERE>
Solution 2. Use openssl
Step 1. Open Terminal and run the following command:
openssl passwd -6 -salt <SOME_SALT_HERE>
Note. The SALT string could be any random string, just make sure not to be a short one.
