A place for developers to talk about building on Farcaster.

/dev

what would be the best way to encrypt a cast, so that only a set of selected fids can decrypt it?

(ofc not in warpcast, warpcast would only see gibberish)

2. whats a good algo for that? ideally with a js implementation out of the box
4. will you hate us if we use it as a growth hack?

A rudimentary v1:

- create a new client and request a new signer for each user in the secret group

- client manages a key in its backend to encrypt all casts posted via client

- users are able to read decrypted versions of the casts

- Map it to a FIP-2 not on Warpcast to reduce timeline spam

haha you are right, but we want to get something running in 2 weeks and with 10% of @cassie's brain while implementing other things as well

give a js lib to your script kiddie (me)

Doesn’t this start to sound like a group version of the Direct Cast mechanism 

(triple ratchet designed by @cassie)

I’m not sure, but my sense when listening to explanations of the scheme, that it can/wil be multi party. (??)

zk zk something

I would love bud something like this into herocast

Isn't this like token gating or group casts?

Sounds like Broadcast Encryption
