> What am I allowed to use as primitives to compose systems that require cryptographic functionality? The problem isn't the primitives, it's the act of a custom composition. The problem isn't whether AES is used. The problem is whether you're writing code that interfaces at the level of 128-bit blocks.

Talk to an expert to guide you through the design and/or implementation of a tool for solving your specific problem. But don't expect everyone writing for a general audience (read: Hacker News comments) to roll out a bespoke solution for your specific use case.
