Is there some way I can hash the contents of my computer so that the police can't confiscate it and dump CP or whatever and frame me?
Like some sort of automatic updating hash system that connects to a personal fileserver, cloud server, and saves a hash file on the computer itself, so that I could show in court that files were added to my computer after it was confiscated and I have the hashes to prove it happened.
The police really does that sort of things in your country? I don't know about cloud and stuff like that but you can use something like IsoBuster to hash your HDD, see pic (I'm sure there're other programs that can do the same too).
You can probably automate the hashing process every X hours or days and even automate uploading the MD5 file to a cloud service of your choice, if you know to use python or java, I guess.
I don't know what Making a Murderer is... uh, assuming it's a TV show; I don't really watch much TV.
I simply distrust law enforcement, for no more reason than they have the opportunity to fuck me over and I would be stupid not to consider and prepare for that eventuality.
Planting evidence has certainly happened in the past, and it will happen in the future. I'd rather not be a victim of such.
I don't have anything illegal on my computer (pending laws changing in the future...), but I'm well aware of what a law enforcement officer could easily do with a simple thumbdrive and some CP copied from the computer forensics department.
If I can protect myself from this, and it's relatively painless to do so, then I want to do so.
And before it's suggested: Yes, I could encrypt my HDD so nobody can even see what's on it, but that wouldn't stop the court/judge from doing something like fining me $30,000 and holding me in prison until I give up the password to them under Key Disclosure laws.
Perhaps a hash created and stored, with timestamp, at every lock/unlock of the device?
I'd honestly be surprised if this sort of security software doesn't exist at the moment. It'd be useful in some situations just for checking your running system to ensure it hasn't been tampered with.
Sounds like you kind of want something like tripwire or dd-verity?
However, if your threat model is corrupt law enforcement, that will not save you, or your kneecaps. Moving will.
Is there any option for hashing besides SHA-1 and MD5?
As I understand things, both have been compromised recently.
It can mitigate damage.
CP's basically life-ending stuff.
If they plant drugs on me or something, I'd still be fucked, but I'd be less fucked.
probably yes but not with isobuster afaik, I don't use linux very much but you probably can do it natively in linux from terminal, windows most likely can't do this sort of operations that require certain permissions, it's probably a very slow operation depending on the size of your hard drive.
