Burp-hash

Warning: some users have reported high memory and CPU usage when running the extension on large audits.

This extension passively scans requests looking for values containing hashes using common algorithms (SHA, MD5, etc.). Observed hashes are reported to the user.

Additionally, the extension keeps track of submitted parameter values, such as usernames, email addresses, and ID numbers. When a hash of a previously submitted value is identified, this is also reported to the user.

Here is a brief video that explains the concept: https://youtu.be/KdgeipzmESE.

Requires Java version 8
