Welcome to Maskbook! Early Access version is open for testing right now. Expect the formal release within September 2019!

Encrypted & Decrypted Automatically

Maskbook allows you to encrypt content when posting on You-Know-Where. Only you and your friends can decrypt them. Not even developers of Maskbook.

Step 1

Install Maskbook

Step 2

Verify account ownership

Step 3

Start posting encrypted posts

Why We Should Encrypt

We might have nothing to hide. But we also have nothing to surrender. And they must have nothing to steal.

Reason 1: Privacy Stealth

Reason 2: Mass Surveillance

Reason 3: Public Opinion Manipulation

M for Masquerade, V for Vanquish

Only we can save ourselves from You-Know-Who. This mass persecution shall not last forever. Rise and end it, once and for all.

Will you join our crusade?
Who will be strong and stand with me?

Do you hear the people sing?
Say, do you hear the distant drums?

Only we can save ourselves from You-Know-Who. This mass persecution shall not last forever. Rise and end it, once and for all.

I thought what I’d do was, I’d pretend I was one of those deaf-mutes.

Explain Like I Am Nerd

Alice installs Maskbook.

Upon initialization, a SECP256K1 keypair is generated automatically.

Alice publishes her public key in a post or in her bio.

Bob, a friend of Alice, follows the same procedure.

When Alice posts, the content is encrypted with a randomly generated AES-256 key.

Alice then chooses to whom (Bob in this case) the content should be readable (default: all friends).

Alice’s Maskbook automatically encrypts the AES-256 key with Bob’s public key via ECDH.

Alice then creates such a post containing the cipher text.

Alice's Maskbook sends the encrypted AES-256 key to Bob over peer to peer data transfer over GUN.

Upon receiving the encrypted AES-256 key, Bob’s Maskbook decrypts the AES-256 key.

Bob’s Maskbook then uses it to decypted the cipher text.

Task Done. No president is elected during the process.

What is Maskbook?

Maskbook helps you protect your privacy against whichever social network platform that earn money by stalking you. These social network giants make hundreds of millions of dollars every year by peeping into your daily activities on their platforms but never share you the revenues.

They are providing free services, aren’t they?

You are right, but providing free services only costs a little — they earn much more money with your online (and even offline) behavior data, which can only be legitimately owned by you, and should only and solely be at your direction. We should stop them exploitating the value of our data.

So, what do you do with Maskbook specifically?

We have made the browser extension and the mobile apps to enable you to post encrypted messages on various social networks that only your expected recipients are able to decrypt and see the original message. In short, you are turning these social networks into tubes!

Is it allowed? Will they ban me if I use Maskbook?

There is no allow or disallow — they will have to accept it because the last enemy for them is the users. If they ban you, it means that they could ban all the other billions of users — smart users like you would soon panic and run for exodus and look for alternatives. Popular support from the users is the most valuable asset for them — that’s why they will never massarce users if there is another option.

Why are you so sure?

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Ownership of Computation, Liberty of Encryption, and the Pursuit of Privacy.

Can my friends read my posts if they don't have Maskbook?

No. That is why we need you to broadcast such a (great) tool to your friends! We really appreciate. (MAKE PRIVACY PROTECTED AGAIN!!!)

Will you be able to see what I am posting?

No. Absolutely not. Unless we are friends. PERIOD. We are providing such an end-to-end tool for you so that all the encryption/decryption processes are conducted on your own computers, and these social network platforms are nothing more than tubes for data transmission (read: "transport layer"). All the transmissions and synchronizations are powered by GunDB, a decentralized database that stores and synchronizes the public keys of Maskbook users. You may consider it a cloud vault (read: "Amazon S3") which helps you store publicly available data. In order to ensure service stability, we run a node in the GunDB network as a superpeer with no privileges than other superpeers.

I still don’t get it?

In short, locally, Maskbook helps you encrypt and decrypt messages and GunDB simplifies the process of authorizing recipients to decrypt. Those social network platforms work as an infrastructure like ISPs (e.g. AT&T) that help you store and deliver the encrypted messages so you and your recipients can access them anywhere and anytime.

Nice. Is it free?

YES!!! We will never charge you for this tool and will always release future versions of Maskbook under AGPL 3.0, the most-free license for free software as endorsed by Free Software Foundation, so that more developers or even non-developers can join the development and help improving the software.

Can I use it on mobile devices?

Sure. You may get Maskbook mobile app for iOS and Android.

What is your name again?
