BTW you can use hat.sh website to encrypt a file with the browser on any device including phone (to decrypt you will have to visit the website) and the website runs locally on your browser so its not sending the file to any server. Source: about 1 year ago

Hey so when looking at xchacha as it seems to be getting more and more popular in terms of adoption for securing files/messages etc. I noticed that when experimenting and testing file encryption with applications like dexios picocrypt and hat.sh that none of the files could be read/understood by other applications. While this doesn't happen with alot of other apps/algos likes aes afaik. Source: about 1 year ago

I usually use hat.sh in the browser. Source: about 1 year ago

Hey so I see that the website recommends picocrypt which uses xchacha20 and its made me go on a little bit of a rabbit hole of xchacha and how it compares to aes. I've also noticed that xchacha is getting adopted very quickly; companies like google; nordpass etc are using it over aes. Does this mean aes is on its way out? Why would a person/company move a lot of their systems to this honestly brand new algorythm... Source: over 1 year ago

I second this comment. https://hat.sh is probably the easiest. Especially if you are not able/allowed to install apps on your device. Source: over 1 year ago

What lessons can we take away from my story? They are, in fact, quite simple and obvious: merely deleting files and quick formatting is usually not enough when disposing of or selling hard drives. For more assurance, it’s better to perform a full format (in modern operating systems, of course). And for the truly paranoid, there’s the good old console utility SDelete from the Sysinternals suite or a tool named... - Source: dev.to / 8 months ago

I assume you were using a dynamically expanding disk - if so just note it won't dynamically contract just by deleting files. To shrink the drive you will likely need to run sdelete -z on the drive inside the VM to clear the free space, then edit and compact the VHDX. You will need to be able to boot the VM to run sdelete though so you'll need to temporarily move other files off the drive, or move the VM files to... Source: about 1 year ago

You can always download sdelete https://learn.microsoft.com/en-us/sysinternals/downloads/sdelete and do an overwrite pass just to be safe. It'll take a while but you can do other things while it's running. Source: about 1 year ago

My understanding is that it doesn't completely solve it. I don't have time to dig up an authoritative source for this claim — hopefully this superuser comment will suffice. I believe that you can achieve something close to a secure erase by filling up your SSD to 100% capacity with data before deleting; the utility sdelete supposedly does this when using the -c option.
