This will change all the password that are the same in one execution:
Code:
OIFS="${IFS}"
IFS="="
awk '/^Password|^hostPassword/ {print $0}' test.file | sort | uniq | \
while read key value
do
        echo "Changing -> Key[${key}] Value[${value}]"
        newPassword=$(echo "${value}" | openssl enc -aes-128-cbc -a -salt -pass pass:wtf)
        searchValue="${key}=${value}"
        sed -i 's#^'"${searchValue}"'#'"${key}"'='"${newPassword}"'#g' test.file
done
IFS="${OIFS}"

This uses linux "sed -i", which changes the file "in place".

I hope it helps!
