History

BleachBit was first publicly released on 24 December 2008 for Linux systems. The 0.2.1 release created some controversy by suggesting Linux needed a registry cleaner.

Version 0.4.0 introduced CleanerML, a standards-based markup language for writing new cleaners. On May 29, 2009, BleachBit version 0.5.0 added support for Windows XP, Windows Vista, and Windows 7. On September 16, 2009, version 0.6.4 introduced command-line interface support.

Technology

BleachBit is written in the Python programming language and uses PyGTK.

Most of BleachBit's cleaners are written in CleanerML, an open standard XML-based markup language for writing cleaners. CleanerML deals not only with deleting files, but also executes more specialized actions, such as vacuuming an SQLite database (used, for example, to clean Yum).

BleachBit's file shredder uses only a single, "secure" pass because its developers believe that there is a lack of evidence that multiple passes, such as the 35-pass Gutmann method, are more effective. They also assert that multiple passes are significantly slower and may give the user a false sense of security by overshadowing other ways in which privacy may be compromised.

Hillary Clinton email controversy

Bleachbit was used to erase emails on Hillary Clinton's private server during her time as Secretary of State during the Obama administration.
