Thanks for the link! Funny to see that someone already thought of this attack in 2022

Very clever! I am the author of one of the older guides https://blastrock.github.io/fde-tpm-sb.html . I was wondering about the solution you propose which seems a bit complicated t…

The encryption/upload is streamed, but the download/decryption is not, we will work on that. Thanks for the link!

Actually, Filekit is meant to be integrated into an application, and that application is responsible for delivering JS and handling identities, not the Tanker server.

No, the unlock key is for the user to keep, and never be transmitted by anyone else than the user themselves. If you do the transmission, it's not end to end anymore. This option i…

TweetNaCl is roughly equivalent to libsodium, on which Tanker builds. Tanker is easier to integrate into your app because it takes care of key sharing, multi-devices, user group ma…

> how the Trustchain Private Key is "obtained". The Trustchain private key is generated when you create a Trustchain. It is generated on your machine. You can try it and create a T…

You are right, you'd still have to trust the webmail/chat provider if you want to chat securely. Tanker still protects against data leaks from the app servers in this case. We also…

Tanker developer here. We use libsodium as our underlying cryptographic library. It uses XChacha20/Poly1305 for symmetric encryption, Curve25519 for asymmetric encryption and signa…
