comment How do we know a cryptographic primitive won't fail suddenly?
@fgrieu Would it be ok to say that there is a single family of algorithms, the one-time pad and essentially equivalent variants (the key point being at least as much key material as payload, hence impractical)?

comment Asymmetric cipher with multiple public keys
@RickyDemer Why ask me here and not there? Anyway: so what? I only changed the title and the tags. I shrunk the very long title to the main point of the question, which is that it isn't enough to specify the password and “AES” in order to have compatible tools. If the IV was the only variable, all tools would be compatible in practice since they pretty much always prepend the IV to the ciphertext.
