That's some great feedback, trompetenaccoun. Slik's file storage is powered by Storj and Filecoin. About encryption, would love to hear what part you find missing in the 3 protocols for backups, sharing, and multi-device support, mentioned in our WhitePaper.

We're constantly improving our WhitePaper to provide as much clarity as possible about our systems and algorithms.

We had set lifetime storage for 10 years, and have clarified it on our website to prevent it from being misleading. Thanks a lot for your inputs! :)

If you say it's lifetime and then have to explain it as being 10 years, it's still misleading. Just take out the word 'lifetime'.

The chances of me trusting a technology company, especially a startup, especially especially one doing anything on blockchain, to provide a lifetime service is effectively zero. Annual pricing is fine; if you want to go crazy offer two or three years.

"lifetime" meaning "10 years" makes no sense at all. It makes your company seem incompetent or badly intentioned. Just say "10 years" if that's the time period.

Thanks for the great feedback Gary! We'll work on it. :)

> Slik employs authenticated symmetric encryption. We use AES block cipher in Galois Counter Mode (GCM) with 256-bit key for all of our encryption operations

That plus the high level overview of the algorithms seems fair enough for a whitepaper

Although I don't get what additional security is gained from using an additional symmetric sharing key in protocol two. Isn't the key gonna be encrypted anyways with the temporary public key from Bob? Also which protocol is used for the asymmetric encryption?
