DRM Explained - How Netflix prevents you to download videos Part 2

Hi Mehul can you make a video on system design or any improvement or optimization you applied in codedamn platform

finally i am first one to comment

DRM: S1 E2

You are the 🐐

Bhai n to tamacha sa maar dia 😂

Looks like you are so angry.But your content is amazing 🤩

Hey can you make video on rate limiting software based and hardware based which is good or bad?

dont waste your time on people that waste their time in the internet trying to sound clever. I saw the first video and I right away understood the message you tried to convey. Any comments trying to deviate from that point are just spam. Cheers🎉

I think people donot understand the concept what they do is it can be done like that way or this way everything possible in this world if you try do, like I did not know about DRM now I know about it and I am glad that I get the info about DRM.

I didn't really saw any comments on the first video, but I am really suprised to know that such a great video received so many negative comments.

I wanna build a automation tool like zapier . Can u make a vid abt how what tStack to use.

Hey @codedamn can you make a video on how people who upload on torrent, upload a movie on a similar day of ott launch , how do they get the Netflix / prime version

Lol i learned a lot from part 1;
Those comments were from pseudo intellectuals

What are these people? That video was one of the most informative I've seen in months. People man🤦🏾‍♂

Ye pata hai break karte karte Sikh chuke hai . I just liked the video because previous one was good and you are making change

When we download a video on netflix and try to watch it offline, how is our device able to communicate with the google/apple server for verification (or key) ?

You received negative comments previously because the video was mostly watched by non-technical people, I believe. I bet few developers or engineers made any negative comments. Your previous video was awesome—keep it up!

Mehul I watch your videos I can't count how many things I learned from you thanks pro keep the good things awesome videoo❤🎉

I really appreciate the concepts,the knowledge, the technologies you are mentioning & sharing through your own experience & your product.
Ignore the bad comments & keep coming up with these types of videos.

people dont get it,, I am here for how DRM tech works, not for how to pirate netflix. period.

And then these "cheap" guys keep crying and blaming govt/colleges for not getting jobs.

Anyways, great video as always. Keep sharing knowledgeable content 😊

The reason the video got viral is , everyone trying to break DRM😂 I wastes lot of time to break Spotify's DRM 😢 but I learnt lot of things 🎉

Mehul ignore negative comment

you can't prevent piracy but you can make it that hard that doing that hardwork looks waste, but there are people who who will do that hardwork anyways

Love your videos! If you take suggestions for video ideas, I have one: Workflow orchestration systems like Temporal, "serverless" queues like Inngest, how they both work under the hood, how they are different, the benefits, etc.

It is honestly hilarious to see that people think they are smarter than Netflix lol. These are people who only download pirated content and doesn't even know what piracy is. Bet most of them doesn't even know what seeding is. Screen recording Netflix is just a layman's understanding of movie piracy. Actual piracy is much more complicated than that. What is listed on those pirate websites are not mere screen recordings. They practically play with the insides of the computer and extract the stream from there, which requires skill levels that are beyond advanced. I am not advocating for piracy in anyway but people thinking they know better than Netflix is just rofl 😂😂

Great video mam people who really understand the concept wouldn't critics the Netflix and how good they have implemented the technology.

I did few research on it i will able to extract L3 keys and was able to decrepit 1080 p videos.
Still the L1 keys is difficult as it is stored in TEE .

Next make a video about how DRM in games works
{Online (anti-cheat)/offline(Anti-Tamper)}

I dont like widevine its used by the many streaming platoform , but widevin selling its api keys , that single api key which able to decrypt the any streaming platform files bro. like netflix , udmey , other platforms

some of streaming platform not allowing for liunx os , they know they have loop holes in there software.

amazing sir,,, you are one of the person who inspire me to be a dev -> I switched from Wordpress to React like technologies because of your content. I want to be as good as you someday.. Thanks for inspiring content. Thanks

The main theory behind DRM is, make hacker life little hard.
And that make sense.

Great explanation 🎉

From where did you get the sources to learn such things

are "web-dl" files available on torrents the actual decrypted version of the original file or a screen record or something else?

About the part where you said TEE source code is not public so it’s not easy to reverse engineer. This got me wondering how open source password managers like Bitwarden remain secure. Pass word managers are a cool piece of tech to discuss about, but I understand that it isn’t something you would learn while working on fermion/codedamn

Excellent videos both. I always had trouble understanding DRM. Keep bringing more topics like such

Which 3rd party provider of widevine is used for drm protection in fermion?

Bro u r toooo innocent in this world that thinks "DRM IS BIG THINGS", I KNOW THAT DRM IS CRACKED YES! U HEARED RIGHT DRM IS CRACKED , REALLY 100% SURE
HERE IS DETAILED EXPLANATJION HOW DRM WORKS
ALL STREAMING PLATFORM USES STANDARD ENCRYPTION WHICH IS AES-256BIT,WITH CBC / GCM / CENC / CLEARY KEY MODES WITH KEY ROTATION
AND THIS IS SYMMETRIC ENCRYPTION OK

THERE ARE 3 DRM PROVIDERS
# WIDEVINE -- GOOGLE
# MICROSOFT -- PLAYREADY
# FAIRPLAY -- APPLE

1). WIDEVINE THAT'S OWNS BY GOOLGLE FROM 2010; BEFORE IT, WIDEVINE IS INDEPENDENT COMPANY
WIDEVINE HAS 3 SECURITY LEVEL
-- THESE ARE FOR DEVICES NOT FOR DESKTOP, ON DEKSTOP THINGS CHANGS OK
-- FOR DEVICES , COMPNAY DO WIDEVINE CERTIFICATE PROCESS U CAN CHECK THAT ON DEVICES WITH DRM INFO APP THAT PROVIDE WHAT KINDA SECURITY LEVEL MY DEVICE HAVE L1/L2/L3 ?
1) .L1 SECURITY
--> ( IT USE HARDWARES'S COMPONENT WHICH IS - "TEE-TRUSTED EXECUTED ENVIRONMENT")
FOR EXAMPLE - ARM | TrustZone | Widevine (Google), PlayReady (Microsoft)
Qualcomm | Secure Processing Unit(SPU) | Widevine, FairPlay (Apple)
--> IT GIVES 720P/ 1080P/ 4K PLAYBACK
2). L2 SECURITY ( U DON'T THIS TOO MUCH ON DEVICES ) MORE SECURE L2 >L3
3). L3 SECURITY
--> LESS SECURE DECRYPTION SOFTWARE BASED
--> PROVIDE UPTO 480P RES ONLY

2). FOR DESKTOP ; WINDOWS , MAC ETC
-- THEY USE CDM (CONTENT DECRYTIING MODULE) "cdm.dll file is present on windows with it's signature and this sig encrytped with system pvt key (RSA PVT KEY)"
FOR WINDOWS "ON CHROME"--> U CAN PLAY UPTO 720PRES, ONLY FOR NETLFIX
--"ON EDGE" --> U CAN PLAY UPTO 4KRES , OK

3). FAIRPLAY DRM WORKS ON APPLE DEVICES OK

IN SHORT --
--> DEVICE + L3 SECURITY :
-- ONLY PLAY 480P RES
-- SOFTWARE BASED DECRYPTION OF CONTENT IN REAL TIME
--> DEVICE + L1 SECUTITY :
-- PLAY 720P/1080P/4K RES CONTENT
-- CONTENT DECRYPT IN REAL TIME WITH HARDWARE COMPONENT "TEE"
--> DESKTOP MAINLY FOR WINDOWS, DIFFF FOR OTHER OK
-- IF U DON'T HAVE HDCP 2.2 (or higher), GRAPHIC CARD , HARDWARE DOESN'T SUPPORT DECRYPTION THEN
-- "ON CHROME" U CAN PLAY : 720P RES WITH , SOFTWARE BASED DECRYTPION THAT IS DONE BY "CHROME WIDEVINE CDM" IN REAL TIME
-- IRRESPECTIVE OF THEE LIMITATIONS , NETLFIX ALSO PREVENT >720P RES ON CHROME BROWSER
-- EVEN IF THESE LIMITATIONS, "ON EDGE"
-- PLAY 1080P RES CONTENT WITH SOFTWARE BASED DECRYPTION IS DONE BY "PLAYREADY CDM" IN REAL TIME
-- ONLY FOR EDGE IF U DON'T HAVE LIMITATIONS U CAN PLAY UPTO "4K"

THIS IS JUST ONE LITTLE TINY LAYER OF DRM U CAN DIVE IN THIS ✌

U GUYS SAW SOME PIRATED WEBSITES LIKE
--> RARBG,THE PIRATED BAY,HDHUB4U,MULTIMOVIES,OLAMOVIES
AND U HEARD ABOUT : "TELLY" , "HOMELANDER" THEY ARE RIPPER , ENCODERS
FOR THOSE : "RIPPERV : WHO DO WEB-DL FORM WEB SITE"
--"ENCODER" : WHO MAKES DIFF RES OF THIS DOWNLOADING VIDEO LIKE I HAVE 4K IT MAKES 1080P,720P
-- WITH THE HLEP OF SOFTWARES LIKE "HANDBRAKE"

-- THEY RIP CONTENT ON FIRST DAY RELEASE IN 4K EASILY
-- THEY ALL PRETEND LIKE THEY ARE HACKER OR INTERNATIONAL PERSON BUT THEY ARE NOT
-- ALL THESE PEOPLES ARE INDIAN TRULEY INDIAN

PEOPLE HAVE DONE "RE" ON WIDEVINE CDM AND PLAYREADY CDM WITH L1 ALSO, AND THEY USES CUSTOM SCRIPT
I KNOW WHAT SCRIPT IS BUT I DON'T TELL IT
IT DONE BY SOME UNKNOW GROUP OK
THIS IS 100% REAL

AND PEOPLE BUYING THIS SCRIPT AND USE IT , AND RUN PIRATED SITES AND GUYS U THINK THEY ARE HACKER , THEY HACKER MY FOOT 😂 , THEY DON'T EVEN print("I am devil of my world")

# IN THIS "TELLLY" HE IS SCAMMER NOT HACKER OK WHO SCAM PEOPLE U CAN KNOW ABOUT HIM GOOGLE IT
ON HIM HAS LEGAL CASES , LAWSUIT FROM MAHARASHRA / MUMBAI COURT -- INDIA

WHY ? WHAT HE DID ? -- HE SOLD CUSTOM WIDEVINE CDM + PLAYREADY CDM , API , DEVICE CERITFICATES WITH PVT KEYS
-- SELL GOOGLE ENTERPOIESE ON THE NAME OF LIFETIME FREE
-- HE "MF" SCAMED INOCENT PEOPLE HARD EARNED MONEY NOT FOR INDIAN BUT ALSO WIDELY INTERNATION
-- FOR EG : 1000$ / 2000EUROS THIS IS INSANE GUYS FOR ONE PERSON OK
