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 $?

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.
