Ockam

76 4,347 10.0 Rust

Orchestrate end-to-end encryption, cryptographic identities, mutual authentication, and authorization policies between distributed applications – at massive scale.

Project mention: Tunnelmole, an ngrok alternative (open source) | news.ycombinator.com | 2024-03-21

disclosure: I work at Ockam.
The Portals for Mac app is an example of the type of thing you could build using the open source stack of protocols. The README (linked by parent) links out to all of the relevant parts of the protocol documentation to explain how these work together. The NAT Traversal (https://github.com/build-trust/ockam/blob/develop/examples/a...) part of the README is probably the best explanation of why the free relay you get via Ockam Orchestrator is a useful part of this demo.
As for why would anyone trust this: The protocols are designed so you absolutely don't have to trust the relay. Trust is pushed out to the edges that you control and so you're not susceptible to a MITM attack if something like a relay is compromised. The protocol design for all of this is open and documented, and was independently audited by (IMO) some of the best in the business, Trail of Bits: https://docs.ockam.io/reference/protocols.

Project mention: Cap'n Proto 1.0 | news.ycombinator.com | 2023-07-28

I'm using Cap'N Proto in a message broker application(LcuidMQ) I'm building for serialization. It has allowed me to created client applications rather quickly. There are some quirks can be difficult to wrap your head around, but once you understand it is really solid.
There are some difference between the language libraries and documentation can be lacking around those language specific solutions. I'm hoping to add blog articles and or contribute back to the example of these repositories to help future users in the future.
Check out my repo here for how I use it across Rust and Python, with Golang coming soon: https://github.com/lucidmq/lucidmq
