Why don't watermelons have locks to keep people from eating them
Sorry
+Watermelon They do, it's called a rind.
The wild watermelon was once top of the food chain, having no natural predators able to break into their locks. For millennium they reined supreme, and it was an era of peace and love. Then humans discovered the watermelon. Being naturally curious, they wondered what was inside, so they chose two watermelons with the smallest and weakest locks and forced them to breed. They then took those offspring and once again forced the weakest locks to bread. They did this for generation to generation of watermelon, until eventually we arrive at the modern watermelon, a shadow of its former glory, with no locks to protect themselves.
+NateTheNerdy quite an information you got there. Bravo!
+Watermelon The point of a fruit is to be eaten. That's like asking why stores have their door open.
My dad told me a phrase that I often now also recite (in the proper context): "All locks do is keep honest people honest."
I always heard it as "A lock can only keep honest people out."
I'll be using these from now on
Is your dad a lawyer?
Sounds like this needs to be sent to every politician on the planet that argues in favor of backdoors on encryption, as almost none of them actually understand that _a backdoor in encryption is a backdoor for _*_everyone_*_, and the backdoor _*_cannot_*_ distinguish a "good guy" from a "bad guy."_
i think they know but its still better to give the burglar access as well than having inpenetrable houses for you to do who knows what inside, the internet is a double edged sword
its too free for governments and industries to just trust the users to act responsible and too free to be controlled within the limits of most constitutions which blurres the lines that separate what a state is allowed to do and what not which in turn gives the government too much power for the people to trust it to act responsible with that power
OddlyIncredible You seriously think they are unaware?
And the problem that anyone who's decent at programming can make one way encryption within at most a few hours.
Amen
Which is odd, because physical locks also can't distinguish between a good guy and a bad guy-just someone who can shove the pins in the right way and someone who can't.

Have the software store two copies: one is encrypted with the whatever key the user wants, and the other is encrypted with a public key to which the private counterpart is retained by the angels. Part of the definition of angels is that they won't maliciously hand over their key to the demons. If the lock on your copy is unbreakable, so is the lock on the access-by-warrant copy.
It's clunky, doubling the storage requirement. But the point is to demonstrate that it's possible, not to figure out the best way.

+joojr2779 put a sign that your house is protected by the second amendment.
+joojr2779 Ever watched a fire department perform a "forcible entry"? They can get into a standard locked and deadbolted front door in 30 seconds, they pretty much pry it off the frame. And in the case of a high security door they'll simply go through the drywall next to the door.
Locked doors are more about not being an easy target than being an impenetrable barrier.
furthermore a "private government key" is only going to be "private" for a short period of time, and after that - all locks are open for everyone. also beeing part of of the government/police/whatever doesn't mean you're not a criminal.
+JohannaMueller57 that is my biggest problem with this. the FBI is full of criminals with badges that do the exact same thing the criminals are doing, with the only difference being their stated intent and government sanctioning. its like having a known house robber insist that he have a master key to get into your house quickly and easily, but only for "official business".

Digital locks that wipe information when tampered with is no different than a physical safe that destroys its contents when forcefully opened. As a consumer, it's my decision if I want such a feature.
If the government attempts to make such things illegal, the criminals that want such features will simply create (or hire someone to create) such features.
It's really not hard, you can find pseudo code for encryption with a simple google, so you don't even have to understand how the encryption works to build it.
IMO that feature does more harm than good, since you have unbreakable digital locks, there is no need for such a thing.
@@damnstupidoldidiot8776 What if you are tortured for the password by some organization in the US government that has a history of (secret) kidnap and torture of citizens (*cough* most of them *cough*)? In particular I would suggest a likely candidate to be a 3 letter agencies starting with C (see M K Ultra) that illegally operates on US soil all the time and has said they want everything the America public believes to be false (about everything I guess? it wasn't specific enough but it seems to have been successful and not just in the US). Then you need an unbreakable lock whose box is also undetectable and a decoy box or a box that destroys itself immediate when you give them the wrong password.
@@sadrien You say that as if that's likely to happen to you. I can reassure you that you are 100000 times more likely to forget your password.

The unsolvable issue: Bad people are more willing to do anything to get in, but good people have morals that keep them from using tools bad people use.
Brilliant. Very important to raise awareness of these issues.
Breaking into a terrorists phone today leads to breaking into a "terrorists" phone tomorrow leads to breaking into your phone next week.
The best articulation of the pro-encryption argument I have heard to date. "The nature of the internet is to bring demons to the door." That may be the best line you have ever put in one of your videos.
I feel like it should also be mentioned that we had a master key debacle before: The Blu ray encryption key leak (AKA the AACS encryption key leak). All Blu-rays are encrypted via the same key, a key that "only angels" had access to, as per the video. Of course, one "devil" gets the key, and it's shotgunned all over the internet. Now everyone knows the 09F9 code and can find it on wikipedia. What happens when Snowden releases the cell phone master key to the world, or Lt. Cmdr. Lin sells it to the Chinese? It's amazing how naive politicians are when we have an example from the past week that there are "devils" in our police/intelligence community.
Yeah, we need more cryptographers and/or people who thoroughly understand the mathematics and possible effects the politician's relatively in-practice ineffective or devastating ideas might create to collaborate with lawmakers.
Why would snowden release the master cell phone key to the world when all he has done is argue against government spying and in favor of digital rights? You actually could not have picked a worse person to strawman.
@@blackfalcon1324 Because he leaked NSA data before? I'm not saying he's a bad guy. I think he's a hero for bringing to light what the NSA was doing. He's exactly the sort of person who would leak the master cell phone key because **the master cell phone key allows for government spying**. He'd release it so that cell phone manufacturers would be forced to abandon it, and so that the public would know about it. Point is, whether it's an hero of the people or a spy of the enemy, there will never be a key that "only angels" have access to.
Most politicians are out-of-touch old men who think they know better than anyone and will stubbornly ignore any and all evidence to the contrary

"Forced weakness puts everyone in danger". You really hit the nail on the head when pertaining to gov't policy. If a gov't demands their citizens have phones that they can easily unlock, they are not in the business of protecting their citizens or their privacy.

+falconer02 Right and not just the US government but governments all over the world are following the same path. One of the big issues is trying to separate which ones of our representatives are malicious and which ones are just ignorant. The average age of a US senator is 62 years. Congressperson is 57 years.

I always use a different variation of my password
+Valpas Kankaristo Password's aren't the same as encryption though. An encryption key is basically a password, but is different for each program/website/etc., but is usually something that the person doesn't know. In a perfect world passwords/keys wouldn't be something a human could even remember. That's why more secure two-factor authentication methods are being implemented where there's a chip in your card that has a code that nobody knows (until someone puts it into a machine reader) plus you have a PIN number that works in conjunction with that chip to make the REAL key. Lets say the chip says Aek#949sJ$3i2nns, and your pin is "1239", it could splice them together as the key 1-4,1-4,1-4,1-4: 1Aek#2949s3J$3i92nns

The "done nothing wrong nothing to fear" argument is so idiotic that I can't even begin to grasp it.
Exactly! Everyone has something they would rather other people not know about. Everyone, even the goodie goodie people.
+snelpiller please explain why it's so idiotic because it seems logical to me
+Luke M Because of the point made in this video. There is no such thing as "angels" that would only use this kind of backdoor for good. You might at some point in your life have had opinions or values, or even had some sort of event in your life that you would not want others to know. Allowing these backdoors would mean that these would always be accessible. If you are convinced that your country and or government would never use information about you to pressure you into choices you are naive. An opinion that you have or had could suddenly be used against you. Banning encryption is a huge step towards a police state and furthermore, enabling these backdroors means they at some point would be leaked, allowing for criminals to access your information. Encryption is freedom of speech. Making it illegal only empowers the goverments. They want to use crime and terrorism as a reason for making it illegal but the fact is that encryption is only used for that in very small ammounts on the whole. The bombings in paris were made with conversations through open medias, not using encryption. Encryption is your right to freedom of speech, don't forget that and don't be so fast to trust your governments and hand them the keys to your life, your freedom is nothing that is carved in stone.
+Luke M
There are multiple parts to that.
"I have nothing to hide, so I have nothing to fear" is like "I have nothing (controversial) to say, so I don't need free speech" and a little bit of "they took the Jews, but I was not a Jew. They took the ill, but I was not an ill. They took the gay, but I was not a gay"
So even if it doesn't effect you personally, it can effect society overall.
In our society, most ppl do things that are legal, but they don't want everybody to know. Ppl have committed suicide due to nude image of them being leaked. Now imagine a government or a criminal organization that wants to control ppl or silence their opposition. They could blackmail opposing ppl with private information, or leak private information to change the mind of the public. (An affair; some guild of association, cause they have a communist friend,...)
Think Edgar Hover who had FBI files about every celebrity and politician and used the power of information to intimidate many.
Oh and I don't think it is an idiotic, but a naive argument.
It makes some sense at first sight, so I would always favor to explain why, than to just state, that it is "idiotic".
(Even though I might do that aswell)
Thank you for this video. I'm tired of all these idiots unaware of their own rights that will say "if you have nothing to hide you should be okay with it".

+Princess Luna Then who was it? Every article I've read regarding it points to Cellebrite, Including one site who posted a purchase order claiming it to be related to the case with Cellebrite's US division as the vendor and DOJ/FBI as the ones who contracted it out.
Phone manufactures including finger print locks are a way for the govt to force you to unlock your phone when you have been arrested. Your password as text is considered speech and can not be forced, your finger print is physical evidence.
The thing is that no digital key is fully unbreakable. Yes it is true that current encryption algorithms make it almost impossible for a brute force attack to work, but often what’s targeted instead are the vulnerabilities in the encryption algorithm itself, which is the same for every encrypted key that’s generated. Therefore, if someone can figure out the algorithm that generates the keys, they can use it to reverse engineer your key and break in.
I absolutely love your videos CGPGrey, they're always wonderfully educational and thoroughly entertaining. Also, you have a beautiful voice, you should hit audible up and see if they'll let you narrate a book.

Basic rule: If someone, other than the person with the info, has the decryption code, then it's not encrypted anymore.
Want the data of your company to be safe? Then only people that NEED to access such data can have access to it, everyone else should be blocked. So, giving the government they "key" to every lock, is basically unlocking all lock alltogether.

After that, there are over a thousand methods to defuse said bomb, even blowing it up. If the bomb is just impossible to reach by any means, then probabily it's just so safe that, when it explodes, it will most likely not cause much damage.
Well the code is unbreakable by design so you can't stop it.
Thanks for getting me through an essay about the Fourth amendment of the Constitution because I was able to sort of connect it to this much more interesting topic!
once again grey bringing the voice of reason to the masses.
+brent bousquet
A MUCH needed breath of sanity.
The number of people I argue with about this very subject. Only yesterday in fact. Most folk apparently imagine the "authorities" can and are tracking and recording absolutely everything everyone is doing.
People let their imaginations run away with them.
I don't want angels to be able to access my information either.
Police can enter our homes with a warrant, but nobody leaves their front door constantly standing wide open to let any random person wander in, which is what encryption backdoors amount to.
"we all ideally want police to crack digital locks sometimes" [citation needed]
The disarm code for a nuclear weapon in a major city is on the phone
All sane reasonable people want the police to be able to unlock that phone
The problem is whatever they use to unlock that phone will unlock all phones, thus the problem.
It's easy to think of such situations.
For example: pedophile has location of victim on his phone. Somewhere, a five year old is going to starve to death in the dark, unless the police get into the phone. Do you want them to get it open?
you can argue for literally any police power with that
@@spambot7110 Yes, that's the problem the video is about. There's extreme situations we can all agree it'd be great for police to access phones, but we have no way to ensure that a backdoor will only be used well. Sometimes we want police to be able to get into phones, there's just no acceptable method to allow them to.
i'm saying i don't want them to ever have access. not because it fundamentally weakens the phone against untrustworthy third parties, but because the police themselves are untrustworthy.
Well explained Grey. This video was probably in response to the Apple-FBI debacle, and I couldn't possibly agree more. Freedom over safety.
This is not only about freedom vs safety but also about safety vs safety. A breakable lock would not only take away freedom from all of us but also personal safety. The phone contains just about every information about you that exists. Imagine how easy it would be for bad guys to hurt you if they had it all...
It isn't freedom vs safety. Someone would think that safety is more important and is a valid position. Keeping your privacy is freedom and safety, and cooperating with the police is just "safety". So it would be freedom and safety vs "safety".
The reason I write "safety" is because it isn't really safety. Is what CGP Grey is trying to say. Giving the police the key imply that a bad person would also be able to crack that key, so looking for safety wouldn't be safety at all.
+Broodrooster24 I don't see this as a response to the Apple-FBI debacle. The FBI went through law to try and get Apple to disable the 10 attempts and the device is wiped lock, maybe something that should be a setting controlled by Apple. Once disabled it still would have taken 50 years for the FBI to break the encryption or maybe not. Every device is hackable, even if Apple would rather have you believe that it isn't. I don't want Apple or any other tech company to build in breakable keys, that as this video says would be a really bad idea, but cooperation on not wiping the device after a number of attempts and maybe even advice on getting access to a dead terrorists iPhone, and just his iPhone no one else's, would surely be in the public interest. I don't think any of us want terrorists to operate knowing that they can communicate without being traced do we? Or do we need another 9/11 to make us realise that certain things should not be made untrackable.
+Broodrooster24 Not just that debacle. Some lawmakers have written a bill that'd mandate digital keyholes for the police.
nick012000 There should be some way that somewhere unconnected to the digital world there is a copy of a key, or something that would allow law enforcement after having been through a court of law to obtain said key and gain access. Couldn't this be created as Apple, Samsung, LG, HTC, and others do this before sale, hard coded into the phone itself and impossible to gain access to as it isn't in the connected online world? Do you really want criminals or terrorists to have somewhere they can hide all their contacts and communications so that nobody can find it?
so that's what happened with that untitled project from CGPGrey2
5 Years Later: Not only have most modern countries passed one version of that law or another, turns out it barely mattered to begin with. Agencies have ALWAYS been able to break into phone, they just wanted to make it easier on themselves. Was revealed this year actually that phones are surprisingly easy to break into thanks to different levels of security based on its status n if ud turned it off recently.

@@ng.tr.s.p.1254 Whatever you say, Hun.
Digital information should be considered as part of an individual's mind, not as something he possesses.
Forced entry into someone's mind can be accomplished through torture or drugs but is messy and considered barbaric. It should also be considered illegal by a society that considers self-incrimination and unreasonable search and seizure to be prohibited.
Of course intentional back doors would be economically disastrous. But even if they weren't they should not be allowed if we value individual liberty.
John Bowery so how do we solve the problem?
That's a ridiculous thing to say. You CHOOSE to engage with the internet and have a digital footprint as a consequence. There is clearly a degree of accountability.
@@brangrah1717 Choose? It's a basic necessity in this day and age. I guess you should be accountable for the bank you use getting robbed and the money getting stolen because you CHOOSE to use a bank.

(Like all of your content btw =])
this is one of the most well done grey video ive seen in a long time. funny/clever writing, informative (duh), and it has such a suave atmosphere to it. don't get me wrong, i loved the star trek and "guns, germs, and steel" videos, but for some reason this one really stand out. great job.
This answers all of my questions raised by CGPGrey 2
i get sooo excited whenever i see a new cgp video, its become the sherlock of my youtube life
+Alexander Soyoye CGP Grey holds the Sure-Locked guarantee of a worthy view.

My new favorite CGP Grey post, which is saying something. Great work.
Presumably I'm not the only one here who would buy the CGP Grey Phone in this video?
For a minute I thought you are lost to the Dark Side ... I am glad that you didn't.
"Where'd all the files go?" X'D

I really liked the music of this video. It added a nice feel and kept the energy up throughout the video. You should consider using more like it in the future. Keep up the good work! 😀
My milkshakes bring all the demons to the yard
But is it better than mine?
Is that a cokiecliker reference
I was part of a criminal trial and while I was in a mental hospital they said they needed my password to my iPhone 4. They said if i didn't give it to them they would break into my phone and the way they were going to do it would break my phone... I didn't want them to open my phone... Does this mean I never had to give the court my password?
+Alex Mateo Obviously.
grey, i dont know how to do it, but youve always been my favorite youtuber. everyime i watch a video i learn so much useful information! thank you!
Who checked that they locked their doors after the first 10 seconds?
They said it was one phone, one time.
We now see the lie.
I saw it coming from day one.
"Quantum computing"
(F yo encription)
-cgpgrey
+Jelle Verest Well it is correct... Once Quantum Computing is "here", current encryption tech will be easily cracked within a few seconds, no matter how long or complicated the password is.
+Tetra Sky yeah, but I just wanted to point out one of the little Easter eggs he always puts in his videos, still that you for explaining :p
Funny password trick for making sure you have different passwords on everything but it's easy to remember: Take you favourite word, Write it with a capital first letter. Take the first and last letter of the site/app the password is for and write those. Take three numbers from your phone number. Big letters, small letters and numbers, but easy to remembers even as you end up with codes like Titfk876, Titye876 etc
honestly requiring caps and numbers and special characters is unnecesarry. what you really need from people is longer passwords.
allhorseseatwelshgrass
is dramatiaclly more secure than
ssZx12k
@@ymmijx6061 if one of your accounts are compromised and the site or platform doesn't encrypt password information, length doesn't matter. When the leaked information is sold by the hackers, others will try to use the same password for other platforms. The real winner is variety. Which is why a formula securing variety is smart. Big and small letters is just because some platforms require it. So adding it to your formula makes sure you can use it anywhere.
hope companies take heed to this video....

thanks for using the original sick figures this time around :)
+ CGP Grey Great video, as always, your videos are so interesting with a fantastic blend of audio information and visual story. It's thought provocative in a great way.
How digital locks work is actually really simple:
Pick two huge prime numbers, and I mean, massif. A magnitude of 10^99 or so, the higher the better. (if you find a new prime, you can sell it for a lot of money for this reason)
The product of those two primes is the lock, each prime is the key. Present the lock with a number, and the lock will test to see if it's a key by dividing the lock by that number. If the answer's an integer, it's a key, otherwise, it's not.
this works because:
1) a product of two primes will only have those two primes as non-trivial factors so no other factor can be found
2) while dividing one number by another is easy, there is no mathematical function to find a non-trivial factor of a number, except trial and error. It's much easier to verify that an answer is correct than to find a correct answer.
Non-trivial factors of a number are: the number itself, and 1.

Angel420Toker yay, knew it, one of my fav games, very obscure, but good
I love the "good. Luck. With. That"
CGP Grey forgot to mention the fact that criminals with a strong enough will will always be able to circumvent encryption backdoors whether it be by using another program, making their own or using older or foreign hardware to communicate. It simply reduces privacy for the majority of the population who can't be bothered to do such things.
