Hi everybody ! Here’s a quick method for generating encrypted passwords that are suitable for things like /etc/passwd
. I realise that this isn’t terribly complex, but honestly, I always forget how to do this until I actually need to do it – so here’s a reminder for all of us. 🙂
#!/bin/bash if [ "x$1" == 'x' ]; then echo "USAGE: $0 'password'" exit 1 fi # Get an md5sum of the password string; this is used for the SHA seed. md5=$( echo $1 | md5sum ) extract="${md5:2:8}" # Calculate the SHA hash of the password string using the extracted seed. mkpasswd -m SHA-512 "$1" "$extract" exit $?
I have named the script as password..when it is run.it is throwing below error
USAGE: ./password ‘ ‘

Hi Mahesh,
You need to give it the string (i.e. password) that you wish to encrypt – it will not generate a password for you, only the hash of the password you specify.
