↳ In-reply-to » @andros I have really tried to get behind it. For an implementation for my TwtxtReader (PHP) I simply lack the knowledge of the standard-openssl parameters. All my solution approaches require “nonce” or “initialization vector” on one or the other side. In addition, the “magic numbers” (“Salted__”) were not consistent in my tests.

If I keep the “nonce”, I can decrypt a message with the shared key, like in the direct message specs.
But that is not how it should work. 😒
