    It appears Schneier initiated the “trust list” of products he used, including TrueCrypt and Bleachbit, in a September 06, 2013 “The Guardian” piece titled “NSA surveillance: A guide to staying secure”, but within a context that open source products are usually presumably less susceptible to coercions to insert backdoors or “forget-to-run” code…not that anything on his list is de facto perfect in default-setting operation.

    Many blogs and review sites describe BleachBit as originating as a CCleaner for Linux, and since becoming cross-platform keep equating its non-self cleaning capabilities to CCleaner without additives of “CCEnhancer”; as for what BleachBit itself claims at its own site re inability of anyone to recover data after just one layer of its erasure scrambling, note currently BleachBit underscores that FAQ with a date in 2010…four years old, four years prior to Passware inter alia ability to recover TrueCrypt keys from a container hiding in randomized data (such as cleaners overwrite spaces with).

    But you’re quite correct BleachBit at least can get rid of its own settings, unlike most other cleaners; where this is a concern for users, there being differences in algorithmic dynamics between spinning HDDs and static SSDs, a user should run something like “Recuva” after using BleachBit and ensure nothing like cluster tips can be recovered from overwritten space…if anything still shows up, a competent utility for then overwriting free space and resetting all sectors to “zero” should be used. It’s possible BleachBit may not overwrite some files at all, as its site at another security FAQ uses another years-old post comment saying it can’t overwrite compressed files but that’s not an issue because “NTFS disks are rare”…is that true anymore in Windows following XP? So someone getting rid of even zipped job search applications should verify efficacy of erasure to prevent personal data falling into hands of hackers or plain snoops/thieves…if you can see with Recuva, so can they.

    Thanks for highlighting a cleaner which can actually clean after itself, and I hope my nittering caveats are somehow of use. Cheers!

    I haven’t heard/tried about this Bleachbit before.
