How to create openssl md5 password hash to use in /etc/shadow using bash

Very useful in embedded and other non-standard deployments. The above makes a random salt of 14 random characters from /dev/urandom (you can change the -14 to whatever number of characters you want for your salt).

openssl passwd -1 -salt `< /dev/urandom tr -dc _A-Z-a-z-0-9 | head -c${1:-14};echo;` YourPassword

Output:

$1$eW-ScuyL$f/iKMJ5mbJ..7bSzvX6EO0
