#Cryptography question: I would like to use libsodium for secret-key encryption, but it requires a nonce, and I need the encryption to be deterministic/convergent (for deduplication).
Is "deriving the nonce from the data by hashing it" a reasonable solution to this problem, or does that have some issue I am not aware of?
@joepie91 iirc ed25519 does exactly that
@joepie91 oh i completely missed that youre talking about secret key crypto, oops
