 What are the openssl command line parameters which would produce the same key as the GenerateSymmetricKey["password"] function? For example, key = GenerateSymmetricKey["password", Method -> <| "InitializationVector" -> None, "Cipher" -> "AES256", "BlockMode" -> "CBC"|>] ; key["Key"] Produces the key "7wUOXiuJb4qDpJSmxq3QULZuLxcgUnWUwle4pLn53Kc=". How could I get openssl to produce the same key given the same password, either in Hex or base64 format?
