Question: What is the purpose of blackbox_shred_all_files? about blackbox HOT 8 CLOSED

The output lists files that were decrypted and are being shredded. For example, if you have many encrypted files but none have been decrypted for editing, you will see an empty list.

I've changed the output to remove the "encrypted files that were unlocked" list. I think it is just confusing.

Hmm I'm still confused on what the command is for.

What does "shredding" mean in Blackbox terms?

I've changed the output to remove the "encrypted files that were unlocked" list

So it will be like this?

$ blackbox_shred_all_files
========== FILES THAT WILL BE SHREDDED:
========== DONE.

So the way to reverse a post_deploy is just to rm the decrypted files manually?

Thanks.

"shred" means to "rm" the file, but doing so in a secure way.

Specifically, it means writing zeros over those blocks of the disk, then unlink()ing the file. Writing zeros over the blocks is kind of difficult because the operating system optimizes disk writes in a way that makes it difficult to make sure the correct blocks are zeroed. To that end, Mac OS X has "srm" and Linux has "shred". The script uses the right tool. If neither exist, "rm" is used as a last resort.

So the way to reverse a post_deploy is just to rm the decrypted files manually?

Either do it manually or run blackbox_shred_all_files.

Hmm ok, thanks. Any idea why blackbox_shred_all_files isn't removing the files decrypted by blackbox_postdeploy for me?

I'm unclear what you are describing.

Is the filename printed in the "FILES THAT WILL BE SHREDDED" list but not being deleted?
or
is the filename listed, but the file is then still on disk after blackbox_shred_all_files is done running?

from blackbox.

I'm confused as to why the files are listed under "ENCRYPTED FILES THAT WERE UNLOCKED", but they are not being deleted (i.e. They are not listed under "FILES THAT WILL BE SHREDDED"). The files were unlocked via blackbox_postdeploy. Or does shredding only delete files that were decrypted by the blackbox_edit* commands?

from blackbox.

The message was misleading. It should have said "Encrypted files".

Get the latest release and you'll see the messages have been reworked.

Updated. Thanks!
