I had a fantastic discussion with @SealdPrivacy about implementation details when implementing End-to-end Encryption #e2ee
The devil is in the details, as often in security and cryptography 😅
Thank you so much @ReboursT and Mehdi, you rock 🤘

#TipOfTheDay 💡: Allow users without Seald identity to encrypt data.
The anonymous encryption SDK enables your application to provide a way for users without Seald identity (unregistered users or users who are not logged-in) to encrypt data for users with a Seald identity.

You can also use it to have your server encrypt data for your users, for example when you collect data for your users from external services.

#TipOfTheDay 💡: How Seald ensures that no-one can perform a man-in-the-middle attack?
Seald created the "Sig-Chain" technology, an immutable register that records all activities such as adding an identity, joining a group, renewing keys, and more.

This signature chain is unique to each user, safeguarding against the possibility of a man-in-the-middle attack.
The "Sig-Chain" serves as a mechanism that enables the verification of a user's entire set of public keys simultaneously.

As well as any subsequent public keys that may be added, following the TOFU (Trust-On-First-Use) paradigm.

#TipOfTheDay 💡: Accelerate the creation of sub-identities.
To accelerate the creation of sub-identities, you can pre-generate the private keys by calling the seald.preGenerateIdentityKeys() function in advance.

In case a user has a very large number of devices, or re-logs in very regularly, we advise you not to create a separate sub-identity for each connection, but simply use the identity stored on SSKS directly.

On voulait migrer à @Sendinblue_fr pour nos emails transactionnels chez @SealdHQ. "C'est français, ça doit être bien niveau vie privée". Que nenni !
Ils ajoutent un pixel espion dans chaque email, et voici ce qu'ils me répondent quand je râle. @CNIL qu'en pensez-vous  ?

#TipOfTheDay 💡: Improve the speed of a Seald identity instantiation.
To improve the speed of instantiation, you can use « databaseRawKey » instead of « databaseKey ».
This avoids deriving the « databaseKey » with « scrypt » which is CPU intensive, especially on mobile devices.

Note that « databaseRawKey » must be the Base64 string encoding of a cryptographically random buffer of 64 bytes.

That's often how it goes 🤦
Before a data breach -> Not the budget, not the time, not the priority!
After a data breach -> We don't want it to happen to us again, we do what's necessary. Get over here 💰

"We'll do a pentest at the end to secure the app."
No.
It's like building a building in Japan, and only looking at the end, if what we did is seismically secure 😅
Security in an app, it's thought out from the beginning.
No ?

Soon @messenger will be more confidential than most chats in e-health apps.

"I don't have time for cybersecurity."
Stop ✋
You'll spend more time repairing the damage after a cyberattack than you've saved by skipping cybersecurity.
