How to avoid exposing the passwd when using curl to run an RTC query on the command line ?

• The ID & passwd are hardwired into the batch file, we just wonder if we can somehow avoid the exposure of the passwd either through encryption or via LDAP ?
• Also this script is great for automating collection of the query results.
• But to fulfill its original intention, picking up the Time Spent  as a measure of the RTC performance, it is not a true measure of the performance: As the majority of time spent is on exporting/creating the CSV file not to run the query. Have tried a query which run for 10 secs took 5 min to export to a CSV file on webUI, took 12 min by this script.
• Not familiar with curl, and had tried to modify the batch file in vain to dump the retrieved infos: Is there a way to just time the query, separate and isolate from outputting the results into a csv file ?
