License Go Report Card GitHub release

gowipe is a simple self contained tool to securely wipe files and directories. By default it renames and overwrites files and directories 30 times and uses the secure mode, which uses strong random bytes for the overwriting process. Gowipe writes as much bytes into a file as its original size.

You can tweak mode and round numbers. Other modes are zero, which uses zeroes for overwriting (not recommended) or encrypt which encrypts the data using ChaCha20Poly1305 and a strong random key. This is the most secure but also to slowest mode.

Although you can use gowipe on SSD disks, it doesn't make much sense. To wipe such a disk you have to resort to other means. But you can savely use it on magnetic discs or usb drives.

Of course there are many other such tools available, this one is insofar special as you can download a pre-compiled binary without any library dependencies. This allows you to wipe files on systems, where you cannot install a wiper via some package management (such as appliance systems or vm's).

Overwrite the directory vhs recursively 50 times using strong encryption and verbose output:

gowipe -c 50 -E -r -v vhs
Wiped vhs/help.png (355011 bytes)
Wiped vhs/rec.Dockerfile (348 bytes)
Wiped vhs/rec.gif (3533338 bytes)
Wiped vhs/rec.tape (852 bytes)
Wiped vhs (4096 bytes)

Although I'm happy to hear from gowipe users in private email, that's the best way for me to forget to do something.
