usm-keycheck.sh

licenseKey=$1
string="not validate your key"
response=$(curl --location --request POST -s 'https://offlineupdate.alienvault.com/cgi-bin/auth' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'next=/files/md5.txt' \
--data-urlencode 'key='$licenseKey)
#echo $response
#echo $string
if [[ "$response" == *"$string"* ]]; then
  echo "INVALID"
else
  echo "VALID"
fi
