`derivedSeedHex` and Messages throws `Incorrect HMAC` error about identity

[farsadf]

So after talking with Ribal from CloutFeed, he told me that there is an endpoint (/get-shared-secrets) to handle this situation; however, such an implementation does have its limitations, primarily a very unusual UX and character length limitation on Nginx.

@maebeam, Is there any sort of alternative method to achieve the same result without this unusual UX?

Hey @farsadf sorry for responding to this just now. Also please tag me for anything related to derived keys in the future. Decrypting/encrypting messages with derived keys doesn't work for now, besides the shared secret endpoint you mentioned. It's a non-trivial crypto problem to have derived keys handle message but I already conceptualized how to make it possible (rotating messaging keys working similar to derived keys but with HD wallet hardened-derivation). It's on my priority list, so it will be possible soon.

@AeonSw4n Fantastic mate! Is there an estimated TAT?
Although I'm not that confident with these sorts of issues, if you think that I might be of help, I'd be more than interested to do some parts.
