I want to show my boyfriend Heathers (he has already seen the film). He is not a huge fan of musicals, so it’s important for me to choose the best version. Which version do you think is best for a newcomer?

→ Heathers Off-Broadway

→ Heathers Off-Broadway, but as animatics (I have a compilation with scenes in between)

→ Heathers West End proshot (to be honest, I’m not a huge fan, I think it’s too camp and it simplifies things too much)

→ Heathers West End with Carrie Fletcher (I prefer this version much better than proshot)

I'm writing an essay about the Signal protocol and I have a problem understanding a concept. While using Wikipedia, it says that Signal uses AES-256 and HMAC-SHA256 as primitives. However, on Signal.org it says that it uses AEAD. So, are AES and HMAC an older approach to encrypting and then decrypting messages, and is this now combined into AEAD? I mean, AES and HMAC are building blocks, and AEAD is a secure way of combining encryption and authentication.

And a second question: the AEAD part of encryption has four inputs — a secret key K of fixed bit length, a nonce N, associated data A, and plaintext P. Is the secret key K the one that is created in the Double Ratchet algorithm?
