If you really wanted to talk to somebody in a "non-decryptable" fashion, could you set up like a channel that encrypts itself with a ton of different encryption methods, keys, etc. (encrypted payloads inside each other)

Signal encryption is its main feature (I think) and how easy it makes it (abstracts handling key transfer and all that), I'm just trying to think through... if I wanted nobody to read what I was saying , would I use an app/target as popular as Signal or something homegrown?

You don't need multiple security protocols (and in fact that is almost always a bad idea). You just need one good protocol and a way to securely exchange the keys. What signal solved for the most part is the secure key exchange.

If you want to talk to one person, you can give them a USB key in person with a set of crypto keys and then use that to encrypt your messages over any transit method and it will be secure.

The hard part is the key exchange.
