SQL injection/mysqli-blindutils/sqli-hap.py

Main article: mysqli-blindutils

sqli-hap.py is tuned to extract a single byte of compressed data per request and requires 255 non-sequential rows in the injectable SQL query's potential result set.

This Python proof of concept uses comparative precomputation to perform blind sql injection, but does not automatically determine the context of the vulnerability or extract multiple bytes in a single request at this time.
