Are there entire operating systems written in a functional language? Why is it imperative languages like C?

tokenized and hashed version of the message message.hashed

so the message “hello world” would be encrypted but you would also get hash(“hello”)+ " "+ hash(“world”) stored on the server? This would mean an attacker could recognize frequently used English words by calculating hash(“hello”) and searching? … I would think the client should tokenize and encrypt the hashes as well: encrypt(hash(“hello”), private_key) + " " + encrypt(hash(“world”), private_key)

Random thought: What if the user submits a merkle-tree, so searching for a sub-string could mean searching for a path in the tree …

Maybe hashes in the tree could be encrypted using a key from the client.

Imo the spartan-protocol is superior to gemini, it enables easy file upload, and is still an upgrade over gopher.

Regarding Encryption: You can simply push that task to an overlay network.

never managed to get the programm running

yeah, I download code and it just does not compile. My environment has not the required dependencies.
